How should I be using cruise control? - LikedDrivingOnce
I observe from various posts in the BR that cruise control is a well-regarded feature on a car by many posters.
I have cruise control on my car and actually, it is easy to operate. Set / Resume / Speed-up / slow-down - are all there and a doddle to use. However, I just can't see the point of it!

Every few months I make another attempt at using it, and then give up in despair. I find that I am forever setting and resetting the cruise control as I get closer to slower moving cars ahead of me, or having to break and drop out of cruise because the Audi lane is already full of cars and I can't overtake, or someone drops into my lane and forces me to break and drop out of cruise.
In fact the cruise control goes on-and-off like the proverbial tart's underwear!

The other problem is that there is nowhere to put my right foot, if it is not on the accelerator pedal. (Left foot has a nice foot rest, but not the right foot)


Could someone enlighten me - maybe I am approaching this all wrong.

If you learn to anticipate traffic and what it will do.... using the cruise slow down function instead of brakes works. Well it does for me.

>>If you learn to anticipate traffic

Agree with that - helps if you keep a decent gap. I never use the brake to knock the cruise off unless it's unplanned. If I'm catching the car in front I'll tweak the speed. By the time I'm needing to use the brakes either to pull up, or a final speed adjustment for a roundabout, bend or whatever, I've already knocked it off without thinking.

The anticipation tends to make for better economy as well - my CRV's mpg readout is about 50 at the moment.

Of course you can do all this with your foot - but I like to give it a rest. Have to remember to keep it somewhere near the pedals though, just in case...

Sounds like the journeys you make dont suit cruise. I use it all the time on motorways, but only when they are relativley clear of traffic.

I find it excellent on the streches of motorway which have an enforced 50mph limit around the Midlands.
How should I be using cruise control? - Devolution
@LikedDrivingOnce, I am the same as you.

The only practicable use I can see is on the motorway, obviously, but most of the time I find it is too busy and too much speed variation to make it worthwhile.

On an quiet motorway I can set it at say 69 on lane 1 but then you soon catch up with an HGV or another car wandering along much slower. I have "notched it down" not using the brakes, but then I end up creeping along at 55-60 to keep my gap, and personally, while not a speedfreak I just can't sit at that speed on a long motorway journey when its a decent clear road and good driving conditions.

Of course I can just pull out in good time into lane 2 but then I feel like I'm dawdling in lane 2 at 69 to overtake a few vehicles at 65ish, and taking forever to overtake, which in turn feels like I'm not making any progress, and although essentially I am travelling at a legal speed, I am sure this will serve to annoy most progressive drivers who think I've become a ML mimser - and quite often you get those who don't want to overtake you in lane 3 (cos that involves going over 71) so they tag along behind you, and now I'm running a middle lane convoy. :-)

My car allows me 60 seconds acceleration grace without switching off the cruise/con but if I am using it every minute or so to swiftly overtake a lorry or lane 1 mimser, then I think why bother using it at all.

I have found it useful in the average speed check areas, and it works really well set at say 49, and I can notch it down and then back up to match the speed of traffic as appropriate without using the brakes at all. But other than that it will be relegated to bullet point feature when it comes to selling the car!

In that case set your cruise control at a speedo indicated 80mph.

You will actually traveling at about 75, well below the prosecution threshold of 79.

Good point AE, I will give this a try at some point. It's my first car with CC, I didn't buy it because of this, just happened to have it, so have only had a few months to play around with it.

I suppose in my mindset, I see one of the reasons of using it at a lower speed is to "save fuel" and keep a smooth journey but understandably I suppose any constant speed is better than constant right foot heaviness. Certainly against my GPS the indicated speed is, as you say, in my favour. Also, while I'm no prude, it's that mental thing of while I'll happily go over 70 to overtake or maneuvere or to "make progress" setting the cruise control to above that is like admitting you are sort of being naughty in advance. If you get my drift. ;-)

But, yes good point I will give it a go at a higher speed. I'm sure I will get the hang of it!

I use my cruise control just about all the time, especially in a 30 limit where it prevents speeding tickets and allows you to observe for hazards. Most of using cruise is about anticipation - you have to dramatically adjust your driving style and plan far further in advance. With regard to overtaking it's often necessary to put on a burst of throttle using the accelerator peddle, as nobody will enjoy you overtaking at 0.5mph more than the person in front.

When on cruise the most annoying motorists are the ones you get passed by on a downhill stretch and then you have to overtake them again going uphill as their speed varies and yours doesn't to anything like the same extent.

That said Cruise isn't ideal in heavy traffic and your speed of cruise will affect how easy it is to use. I can cruise just about all the way from Glasgow to Wolverhampton at a set 70mph almost any time. I find trying to use cruise and maintain speeds greater than the national average is difficult as people at that kind of speed tend to vary far more because of people pulling out at lower speeds and misjudging distances.

At the end of the day if it isn't for you, it isn't, but I wouldn't have a car without it.

- and they often look so 'cross' when you go past them - not realising that it is they who cannot maintain a steady speed, in fact you notice just how many drivers are apparently incapable of doing this even on the relative flat.....

I find that cruise isn't suited to very hilly or bendy roads e.g. a sudden cruise-induced burst of acceleration mid-bend may not be welcome.

I have specified cruise control on cars since 1996, however I notice that a number of manufacturers are dropping it from their standard specs of late (Audi A4 B8 SE, BMW 4 cylinder E90/91 SE for example) - cost saving but also frustrating if you fail to notice until it's on your drive. Although it can be fairly straightforward to retrofit I'm told.
How should I be using cruise control? - CGNorwich
Tempted to respond "not at all". My car has cruise but never really found the point of it. Possibly of marginal use on an empty motorway but even then its not difficult to maintain a constant speed without it. Have just driven to Germany and back and never used it once. I don't like the feeling of lack of lack of control and I certainly would never use in anything like heavy traffic. Would gladly swap it for something useful llke another cup holder :-)

Excellent replies from everyone, and thanks to those replies I have learned something - thank you. I can see more clearly why cruise control has its fans, and also why it doesn't suit the mostly congested driving that I do in London and the South-East.

If traffic were not so heavy, then I could see myself using it....maybe.

It was very nice to see that I am not alone in not using it though. Thanks Devolution and CGNorwich - I think that you actually argued the case better than I did in the original post.
How should I be using cruise control? - Bilboman
Just a couple of things to add to the already extensive and useful comments posted here...
* I use cruise on clear empty stretches of motorway (I hasten to add I live in northern Spain...) as I can then think about everything else except the speed I'm doing. I find it very restful on a 120 kph motorway NOT to have to check my speed so regularly.
* On busier stretches, cruise acts as a check on speed and what I call an "idiot filter": on an 80 kph stretch, I keep at a safe and legal 80 (precise speed courtesy of SatNav!) and simply ignore the idiot charging up my rear, trying to force me to go faster just to satisfy his ego. I don't make any eye contact or make any overt "looking in the mirror" gestures, so he's never really sure I've seen him. (Best way to deal with any bully - ignore him, right?)
After a while he usually realises I'm on cruise and finally pulls back and waits for the next available overtaking moment. When I'm being hassled like this, I find cruise helps me keep my mind off the idiot behind and I know I would otherwise be tempted to speed up and possibly get caught by a scamera (which are becoming quite common in Spain now). (Or do what some BRers like to advocate: slam on the brakes and teach him a lesson!!)
Cruise is best switched OFF, however:
* in any adverse weather (rain, fog, snow) and on stretches which are winding or mountainous.
*on downhill gradients
*where there are frequent "bunches" of cars, which either have no cruise, or else have it set at 7 mph slower than me!
* in town.

It's interesting to read the comments here and see that it worries car drivers just as much as lorry drivers.
I've never had cruise control on a car and would never use it if I did.
I've had it on lorries now though for a few years, and always found myself only using it on long empty stretches of motorway during the night time hours when roads were very quiet.
I know some lorry drivers who swear by it in roadworks with limited speed and in towns to keep under the 30MPH speed limit, but having tried that I found an impending feeling of panic and found myself 'covering' the brake pedal constantly, so it wasn't for me.

The problem for me is that if I see a situation happening up ahead, I want to be able to brake instantly if I have to. Without cruise the lorry would be slowing down from the second I took my foot off the accelerator to cover the brake, with cruise it's still accelerating or at least, maintaining speed until I actually hit the brake pedal and this delay makes me uneasy.
I haven't explained that very well at all :)

I think I understand what you're saying but you could argue that on cruise you haven't got to waste time taking your foot off the gas - you can just go straight for the brake. I guess there must be a fractional disadvantage which could probably be measured in lab, but in the real-world it would be a one in a million occurance where it made any difference.


Personally, I think the speed limiting function on my Merc is more useful than cruise - I don't know how many vehicles have this, but it means that you can cope with varying traffic whithout having to keep an eye on your speed - very useful in motorway roadworks etc.

Only use CC for maintaining a steady speed on motorways ( that are not too busy) and open A roads.

Everywhere else dont.

I have it on the S60, and use it for SPECS stretches, or the odd occasion when I'm on a motorway in late evening. On a run down the M4 a couple of weeks ago in the small hours for example, it worked superbly. Those instances are few and far between though. Most of my driving involves commuting on a rush hour M3 / M25 and you can just forget maintaining any steady speed, or averaging more than about 25 mph most days.

The major routes in these parts are far too congested between the hours of 7am and 7pm to even entertain the use of cruise.
How should I be using cruise control? - craig-pd130

As above, I find it useful in roadworks with speed checks, and on the M42 where the variable speed limit gantries are ... it's a useful means of ensuring your speed doesn't drift upward.

Didn't you worry about what might happen if (God forbid) you started to nod off? Now I'm not suggesting you or anyone else on the BR would drive while tired, and nodding off without CC is hardly advisable. But the thought of being driven off the road or into the back of something under power is a frightening one.

I did have CC on a previous car, and did go through phases of using it when/where appropriate, but I can't say I miss it.
How should I be using cruise control? - Old Navy
As most people have said, appropriate use is the key. Heavy traffic and many A or B roads forget it. Light traffic, average speed cameras, brilliant, Glasgow to Carlisle and beyond, CC all the way.
How should I be using cruise control? - SteelSpark
I'm not speaking from a position of experience here because I have only used my cruise control once! (for about 5 minutes on the North Circular late last week)

I did find the whole experience a bit freaky, not having full control of the car's speed (mainly that when I started to ease of the accelerator for traffic ahead, the car obviously ignored me).

That said, I do think that I will try to use it on the motorway and dual carriageways, when they are not too busy. Due to my inexperience I am not great at maintaining a set speed, and it can sometimes feel like a distraction. There are quite a few 50 mph restrictions on the northern M25 at the moment, due to roadworks so it could also be useful there.

It didn't feel uncomfortable using the cruise control (even though there was a fair bit of traffic), just weird, and I think that was maybe because, as a new driver, I am tending to leave decent gaps to the car in front (nothing extreme, just the good old two second rule).

The CC3 is the first car I've had with cruise control, so you can understand my desire to play with the new toy.

Trouble was I collected the car on a cold evening in March and there was some icy slush on the road.

So I found myself, with about 12 miles on the clock of my brand new car, slewing from side to side on a slippery road as first one wheel spun and then the other.

Happily, there was nothing much on the road and I disabled the cruise before totally losing control.

I still use it, but only in good driving conditions - I wouldn't even risk switiching it on in heavy rain.

How should I be using cruise control? - DP
The spookiest part to a cruise control noob is when you encounter an incline and the system applies power to maintain a constant speed. My father in law has a Golf IV TDI 130 with cruise, and the monstrous midrange torque of the PD engine tends make itself felt even under gentle acceleration with a gentle, but firm push in the back.

It's quite spooky going up Stokenchurch hill on the M40 and really feels like the car is trying to run away with itself. The speed of course remains steady, but it is such an odd feeling having a car apply power by itself.
How should I be using cruise control? - b308
I don't understand the reason to have to speed up to overtake, the whole point with a motorway is to keep a constant speed, its not a side road where you need to get in front of the vehicle in front asap because you are on the "wrong side" of the road, you are all going the same way on the motorway! I set mine on the motorways at either an indicated 70 or 75 dependent on the mood (real 65/70) and just anticipate the traffic and move out when I'm least likely to cause anyone else to have to slow down... it takes practice at first but its not hard and lets face it if you are constantly over-riding the cruise you may as well not bother... which is probably why some people don't like it...

Incidentally, I'd say that someone using cruise properly at those sorts of speeds is probably more aware of the surrounding traffic than most other road users because to use it peoperly (ie not speeding up/slowing down) you have to be very aware of other traffic and their speeds relative to yours so you can keep that contant speed...

Its useful on the relatively quiet and straight roads of rural France. I used to use it quite often on UK motorways years ago, but not any more - too busy. The only time I used it on a recent visit to England was on that long, long stretch of roadworks on the M1 past Nottingham - and that was in deference to the speed cameras.

"Its useful on the relatively quiet and straight roads of rural France"

Poland too has great roads for cruise control, I rarely switch it off come rain, hail or snow. I set it a few kph faster than the trucks and a few kph slower than the cars. That way nobody gets under my feet and trucks don't have to pull out to overtake.

I never pass slower traffic on cruise though, I always kick-down and move back into lane one as soon as poss.

I do a few long motorway journeys per month and I do exactly the same. However, it's a recurring issue that if I pass a car that is travelling slightly slower than me and then I pull back into Lane 1, it will immediately speed up and pass me, and then slow down again, often staying in Lane 2 so effectively blocking me.

It's sure it's not people causing trouble on purpose (although it could easily develop into that) but it happens again and again.

I use CC a lot in my Mk6 Golf with dsg. Of course the car will change gear as well as vary the throttle position as the road varies, which takes a little getting used to.
It also gives my right foot a rest. The golf has a hair trigger throttle from rest, followed by an unresponsive throttle at low speeds which I find makes my ankle ache.

Tried using CC, set to 65mph, in my new Audi (2.0 Tdi CR 170) whilst towing a caravan on a long-distance motorway trip to the South of France. Started to notice a faint, but nasty rattle from the engine on uphill sections of the motorway....realised that the CC senses a speed drop on the gradient and floors the throttle, something a sympathetic driver would probably never do, especially in 6th. Stopped using CC whilst towing, in the interests of engine preservation. Personally, I find CC useful in average speed controlled zones, but don't use it much otherwise. And OP is right, there's nowhere comfortable to put your right foot in the Audi, if not on the accelerator. CC came as standard, but I wouldn't bother paying extra for it.

Got two footrests on the Octavia and tend to use the cruise a lot, even in 30mph zones.
Slightest touch of the brake disengages it.
How should I be using cruise control? - Westpig
both our cars have them..and I wouldn't be without it now. Nothing really to add that hasn't already been stated...practice makes perfect ....and I agree you are more aware of your surroundings and anticipate more when you're using it.

Wife's car's one has the annoying trait of allowing itself to drop below your pre determined limit by a few mph, hesitating and taking a few seconds to get back to the exact speed again if you've overriden it temporarily (e.g. to speed up a bit to pass someone, then want to go back to your original speed), ...this means the person you've just overtaken is now catching you up again and thinks you've throttled off..my car doesn't do that.

Sometimes if someone pulls out into my lane, i'll try to anticipate when to knock the cruise off, then anticipate when to put it back on again, so that I never have to touch the throttle or brake.

>>Wife's car's one has the annoying trait of allowing itself to drop below your pre determined limit by a few mph, hesitating and taking a few seconds to get back to the exact speed again

That suggests the integrator in the controller isn't been reset when the cruise control is being over-ridden. The controller effectively thinks that because you've been going faster than the set speed for a while that it should back off - then, once you've been going below the set speed for a way, the effect cancels out.

X Type 2.0 diesel estate...4.5 yrs old, well out of any warranty...always done it

if you're doing say 70mph on cruise ....;-).... gradually catch someone else up, accelerate manually to get past, then let the cruise take over again (either leaving it to itself from the higher speed or by turning it off and turning it back on again when you're manually doing 70mph again)...it'll momentarily slow to about 67mph, before picking back up the the 70mph

probably not bad enough for me to justify spending much on it....but nevertheless irritating...if it were something they could bung through the diagnostic computer at the next service i'd have it done
How should I be using cruise control? - Number_Cruncher
>>Can i do anything about it?

I would enquire to see if there are any soiftware updates which should be applied to the ECU - I imagine if the car is reasonably modern, cruise control will simply be software inside the controller actuating the drive by wire throttle rather than a seperate cruise control system.

If no updates are available, then, it's not a fault as such, rather it's just naive, or overly simple programming of the controller; a design fault effectively, and you'll be stuck with it - sorry.

Disengaging cruise while you override it will prevent the integrator becoming wound up with excessive speeds it can't correct, but, that's a hassle.

At least the problem hasn't led to any oscillation of your speed or any instability!

How should I be using cruise control? - Lud
Like LDO I don't often find cruise useful on normal SE roads. I still have to try it on a long motorway drive.

And there's my argument about the time it takes to get the foot on the brake:) (Pat (PDA))


If I have to brake to whilst the CC is in use there's a real risk of my load tipping forward - because I'm going straight from accelerating to braking with no "cruising" in between.
How should I be using cruise control? - Old Navy

Eh? If you are on CC you are "cruising". It only accelerates if you have dropped below the set speed, and you should not be accelerating into a problem anyway.

There's a difference between a loaded lorry and a car. I realised that yesterday when I read the posts on here.
I think what us lorry drivers are used to is that as soon as we 'stop' accelerating the load immediately starts to slow us down.

Cruise control does let us drive at a constant speed. I probably didn't explain myself very clearly. Most cars fitted with cruise control tend to be quite powerful - or, more correctly, to have a favourable power-to-weight ratio. Most lorries don't. A fully loaded modern 7.5t truck will have a PWR of 20bhp/tonne, a 44t artic will have around half that figure.

Imagine having your 1,800kg 5-series powered by an engine putting out 18bhp, and you can see where I'm coming from.
How should I be using cruise control? - Old Navy
I think it may be a terminology thing, accelerating = power on, cruising = power off, in truck speak. Feel free to correct me Pat or Dave.

Edited by Old Navy on 15/10/2009 at 12:34

How should I be using cruise control? - Dave_TD
I think you might be right ON. Without CC one generally has to keep the accelerator pedal 100% to the floor to make progress, even lifting the pedal to 75% will cause a truck to slow down somewhat. It was this feeling that I referred to earlier, that the "jolt" of applying the brakes and simultaneously removing all power is much greater than a good trucker would ever allow to happen.
How should I be using cruise control? - pda
That's exactly why I'm uncomfortable with it Dave!

And without wishing to drag up past threads, it explains too why lorries are reluctant to 'ease off' to let another one past them.

No, you were acting as apologist, making excuses for ignorant behaviour.

Tolerance is fine, I have no problems with making allowances for the unavoidable bulk of trucks as they make their way through traffic, but, rolling road blocks borne out of ignorance and idleness is quite another matter.

I hope the next government bans trucks from overtaking on all roads, excepting for overtaking cyclists, and slow moving agricultural vehicles.

No number cruncher, I was most certainly NOT acting as apologist and I don't need an explanation of what that means either.

But, Pat, it explains nothing. It's just another non-reason, like the mythical need to save the seconds it would cost to ease off.

How should I be using cruise control? - pda
Once again NC, you try and put words into my mouth! I didn't defend anything I gave an explanation, albeit one you find unable to understand.

Look at it this way, I have over the years broken downat least a half a dozen times, in an artic, on a single carriageway.
Without exception it's been brakes, wheel bearing or propshaft problems that have brought me to a halt and not allowing me to move.
On every occasion I have caused a considerable tailback of traffic.
This has always resulted in at least a couple of car drivers pipping their horns, waving their arms and on one occasion, shouting through the sunroof at me to tell me I shouldn't park there:) ( at least that's the polite version)

They obviously knew that I'd parked up to annoy them, and their couple of minutes were more precious than my couple of hours waiting to be repaired and on the move.

There's a moral to this tale..........................

I know that even if they had to pay my repair bill they would still think I 'parked' there just to annoy them!

Pat
How should I be using cruise control? - Number_Cruncher
>>There's a moral to this tale..........................

Is there? I don't see any link there at all.

Breaking down is, providing reasonable maintenance has been provided for the truck, unavoidable. Rolling road block overtaking, is , on the other hand, very easily avoidable.

By offering an "explanation", you are, whether you are intending to or not, legitimising the actions of the ignorant and idle contingent among truck drivers.

It's not that I'm struggling to understand, it's just that I don't accept any of the explanations given for these roadblocking overtakes.

Sorry Pat, I'm with NC on this one, I can't see any excuse for the long overtakes. And yes, I have driven a heavily loaded 7.5T and I can see it's a nightmare, but even so, regaining 2 mph is really a non-issue.

I hope the next government bans trucks from overtaking on all roads excepting for overtaking
cyclists and slow moving agricultural vehicles.


Glad it's not just me then.

Idle?....where did that come from? When did you last work 75 hours every week as normal, and get prosecuted for taking 1 minute short of a lunch break!

The moral NC, is that I learned to smile sweetly at abuse and relish the fact the person was so blissfully ignorant, but so sure they knew everything!

Also borne out in your statement above 'I don't accept any of the explanations'!

Now, let's not be impolite and get back to cruise control:)

>>Idle?....where did that come from?

It came from me, borne of my view that a certain type of truck driver just holds his foot to the floor, and allows the 56mph limiter to do all their thinking for them, being too bone idle to lift the throttle for a second, allowing the overtake to happen quickly.

>>When did you last work 75 hours every week as normal, and get prosecuted for taking 1 minute short of a lunch break!

It's been a while now since I had to drive a truck to earn my income, and I'm in no rush whatsoever to get back into the cab. However, that doesn't translate to a blind acceptance of everything truck drivers do.
'I don't accept any of the explanations'!


That's simply because I haven't heard any good explanations for this ignorant behaviour, and I strongly suspect there are no good explanations for it.

>I don't understand the reason to have to speed up to overtake, the whole point with a motorway is to keep a constant speed...

No it isn't! Sorry if this seems abrupt, B308 - I've often appreciated your moderate views and measured expression - but I don't agree with that at all. The whole point of a motorway is to facilitate safe and (reasonably) rapid progress. It's nice if you can also cruise at a steady speed, but can you imagine the chaos if everyone tried to maintain a constant speed? It wouldn't just be the odd inconsiderate truck driver blocking a whole lane crawl past a marginally slower vehicle; it would be every third car driver too.

Once you're out of lane 1, you're no longer cruising, you're overtaking, and you have a duty to other users of the road to complete that overtake in a reasonable time. That means that when you - with CC on or not - approach a slower vehicle, you have three choices:
  • Decide not to overtake, but to adjust your own speed downwards and follow the vehicle in front;

  • Judge that your current speed will carry you past the slower vehicle in a reasonable time, so pull out and carry on;

  • Speed up to carry you past the slower vehicle without holding up anyone else.


I have another worry with using CC out of lane 1; imagine you're passing a line of four trucks when suddenly one starts flashing an indicator. If you're on pedal control, you naturally lift off and slow down a little while you assess whether the driver has seen you and intends to let you pass before he pulls out, and whether you have options in lane 3; with CC, that doesn't happen and it might cost you vital space and time to make a safe decision. Unless I can see I'll have lane 2 to myself until my manoeuvre's complete, I hit the 0 button before I pull out and don't Resume till I'm back in Lane 1.

Sorry, WdB, but I entirely disagree, the motorway is a means of getting from a to b in an easier manner than using other roads because it has no slowing for junctions, etc, "rapid" progress is the bit where I feel that you are wrong... Yes, you can make "rapid" progress if you wish but there is nothing wrong with cuising at less than the max limit, both users are using the motorway for its correct purpose. I would suggest that there is a sizable number of motorway users who already drive at a constant speed - lorry drivers - who are limited to 56mph - and only cause issues for the more impatient amongst us. Actually there would probably be less chaos if everyone stuck to the same constant speed.

Once you're out of lane 1 you're no longer cruising you're overtaking and you have
a duty to other users of the road to complete that overtake in a reasonable
time.


Yes you are overtaking... but that does not mean that you should break the speed limit to do so, if I'm cruising at 65/70 then there is no earthly reason I should need to speed up to get past someone and break the limit just because there is someone catching me up who is... and what about those lorrys you mentioned earlier, or more pertinant to the discussion, coach drivers and those who are towing and limited to 60? Are you suggesting that they too should break the limit?!

I will continue to do my utmost to ensure that I don't delay any other road user, legal or not, but I will continue to do so within the law... If I come up behind a lorry overtaking I will adjust my speed accordingly, and not get wound up about it, I'd suggest that those who wish to make "rapid" progress do the same when they come across someone like me overtaking at the legal limit.
How should I be using cruise control? - TheOilBurner
I see nobody has so far mentioned using a speed limiter as an alternative to cruise control.

On my car, I don't generally bother using cruise control unless I'm on a very quiet motorway.

Instead, I'll set my speed limiter (common on French cars and some German ones) to the speed I'd like to cruise at and then rest my foot on the accelerator enough to maintain speed. This then acts like cruise control, except that if I want to back off from slower traffic ahead all I need to do is lessen the pressure on my right foot, as you would normally.

Plus it gives my right foot somewhere to rest. When using cruise control for ages, I don't know quite where to keep my right foot, concious of the fact that it may not be in a natural position for emergency braking. Using the speed limiter solves that problem.

And if I want to blast past some slower traffic, I still don't need to turn the speed limiter off, as a sharp prod to the bottom of the pedals travel overrides the limiter and off I go.

Works for me.

Ok, I missed that one...
Another Cruise Control Question - Quacker1964
After reading the last one, which got a little heated and a balanced view from both pro and anti camps, I have a hopefully less controversial and straight-forward question.

Is using cruise control more economical/efficient than using the accelerator for the same journey, speed and distance etc.?

I heard elsewhere that it is more economical to travel, say 50 miles at an average speed of 65mph than to use CC for 50 miles at the fixed 65mph (assuming a nice road to do this).

The only way I can see any advantage of the accelerator is at times the speed may drop from 65 to say, 60 before regaining the 65 - and hence the slightly slower speed is more economical.

I would have thought the constant 65 would have proven more efficient over the journey.

As I said not CC or not CC question, but can anyone shed any light on why it may be less efficient as I may be missing something really obvious?

Another Cruise Control Question - gpmartin
This was discussed ages ago (will try to dig out a link to the thread in a minute), and I'd have thought like you that setting the cruise control and letting it get on with it would be more economical. However, it didn't seem to be so simple, and someone even claimed that he could get better mileage by accelerating to e.g. 70, lifting off the accelerator (but keeping the car in gear so that fuel injection was cut off) until it went down to e.g. 60, then repeating, was more economical than a constant 65. Sounded implausible, but he seemed to have assessed this scientifically (well as scientifically as possible when using a trip computer to measure mpg over time while simultaneously driving!).
Another Cruise Control Question - Bill Payer

This is the hyper-miler technicque used by people such as those in the Shell economy contests where they get 2000MPg from go-karts on tracks. It's clearly impractical on the public road.


If you could really drive at exactly 65 "manually" then it would be just the same as using cruise.

But in reality it's difficult and your speed varies. Obviously if it varies down then yuour MPG will go up.

The main thing is that, if driving manually, you could ease off going up hill and gain speed going down hills, while still averaging 65MPH. This should be more economical the ploughing on at a fixed 65, but it would be a very marginal difference.

Moved into the similar thread.
Another Cruise Control Question - Number_Cruncher
>>Is using cruise control more economical/efficient than using the accelerator for the same journey, speed and distance etc.?

The problem is that like is never compared with like. Without running 2 cars side by side one with cruise control and one without, there are too many other variables which make anyone's trip comuter measurements meaningless.

A cruise control will normally produce better economy than a normal driver maintaining speed manually, because the spread of speeds around the set speed is much narrower with cruise control, and hence, less fuel is wasted a) propelling the car faster then the set speed, and b) accelerating back up to the set speed

Switching cruise control on does not change the basic physics which governs how the car burns fuel and produces power.

Another Cruise Control Question - Quacker1964
But essentially - and we're talking non-scientifically here - fair comment to say cruise control on the flat/level where possible will yield better results but switch to "manual" on the "hilly" bits as one can feel the acceleration going uphill and you don't reap the rewards of the incline as the cruise will hold back.

At least theoretically ......
Another Cruise Control Question - Old Navy
Even with oil at $80 a barrel it probably only makes a marginal difference, I would think that CC is slightly more economical. Even if it isnt I will still use CC whenever appropriate, the odd 10 miles or so one way or the other per tank of fuel is worth it for the convenience.
