A driver is hiring a racetrack to prove his car can't do the speed the police claim he was doing.

This just doesn't make sense! I am sure the car could do that speed, and more so, I am sure there are ways and means of proving that the car can't do it NOW, if you know what I mean?

oh dear! could be a mistake, there are a few fast downhill bits at knockhill!
Driver to prove car can't do recorded speed - SlidingPillar
Even if the car will do 100mph, he won't do it at Knockhill. No straight long enough. And that's the case with most circuits. A proper race car you usually gear to do just the top speed and change the gearing for each circuit. Road cars, the top speed is perhaps 2/3 revs in top as otherwise the fuel economy is dire.

He needs Bruningthorpe or perhaps Elvington, but I can't think of anywhere else.

If he was in a 30 limit and police say he was doing 100 the fact that his car can't reach that speed seems academic. He must have been doing well over 30! Might be an interesting case to keep an eye on!

There are precedents. Soon after the first Range Rover came out an owner was nicked for doing IIRC 100 on the M3. He produced a Landrover engineer in court who testified that the vehicle could only do 95, or whatever. He was let off.
Another case was a motorcyclist done for speeding on the M25. I can't remember the ins and outs of the case but they were trying to do him for 95 or so and he admitted to doing 85 but because the junctions mentioned in the 'evidence' were so close together, the police figures did not add up. Something like "I followed him for 3 minutes at 95 between Junctions X and Y"
- the Junctions were too close together for that to be possible.

I can remember reading a national newspaper about a student who was accused of speeding in his early nineties Honda Civic.
But he was let off because he took to a test track (can't remember which one) & tests concluded that it couldn't reach a certain speed.

If the police say he was doing 100mph and his car cannot reach that speed then he probably will have to be let off. They cannot then say "oh it might have been 90mph". Their speed measuring equipment is meant to be accurate.

The man in Madux's post was lucky to get off if he admitted doing 85 IMO! Strange world where you can admit 85 and be acquitted and you can get 3 points and £60 for doing 35 in a 30! However, good luck to anyone who can beat what is jokingly known as "The System".

That article says the guy was being followed at 100mph - the likelehood of that being incorrect is probably less than of a mobile speed camera being wrong, IMHO.
Driver to prove car can't do recorded speed - stunorthants26
So if he can prove that his car couldnt do the speed they say they recorded him at, is he then going to claim their equipment was not accurate?
He is essentially trying to make liars out of the police yes? Im guessing that while he was obviously breaking the limit, they dont have any firm proof of by how much if he disproves them, taking it down to the police having a 'best guess'?

Wonder if he'll "detune" his car before he takes it to the circuit?
Driver to prove car can't do recorded speed - Altea Ego
It has to be said, the chances of a guy in a knackered old 405 getting it up to 100mph in a 30mph limt, must be pretty limited. Ditto the police are a bit foolish by claiming a nice round number of 100mph. Had they just gone for 80mph then guy would be banned and cursing his luck.
Driver to prove car can't do recorded speed - TheOilBurner
I'm guessing what may have happened is that the Police had to do 100mph for a stretch to catch up, indicating that the 405 was actually doing around 80 or so.

It'll be a shame if this guy does get off on a technicality, because there's no way he was doing anything like sane and reasonable speeds, that's seems very clear.

You just wonder how much of a bonehead you have to be before this seems like a good idea to pursue.

There is a problem with VASCAR. It has been shown it is subject to interference and speed calculations can be wrong. Makes you wonder what is wrong with this country when all the speed measuring devices aren't allowable in evidence as they haven't been approved by the home secretary. Still people get prosecuted on technicalities by instruments that are technically illegal!!

Scotland: Police Halt Use of VASCAR Over Accuracy Concern
The Association of Chief Police Officers (ACPO) in Scotland issued a memo Tuesday recommending that VASCAR not be used to issue speeding tickets to motorists. Although the "Vehicle Average Speed Computer and Recorder" is a thirty-five-year-old technology and has been replaced in some areas by radar and laser speed guns, it is still commonly used in the UK and the US. "Until such time that the matter has been fully investigated, a memo has been sent to officers asking them to use alternative speed detection equipment," Strathclyde Police Chief Inspector Andy Orr told the Aberdeen Press and Journal newspaper. VASCAR estimates speed by calculating the amount of time it takes for a vehicle to pass a given distance. The police officer operating the machine flips a switch when a vehicle passes a given point and then flips it again when the vehicle passes a second point. The machine then displays a speed on a small readout. Because the device appeared to depend more upon the skill of the operator to produce a reliable estimate, UK police authorities never required Home Office Approval or accuracy testing for the device. Instead, the VASCAR manufacturer insisted that the "quartz crystal" performed a self-test allowing the device to establish itself as an accurate instrument for measuring speed. That did not turn out to be the case for UK officials who recently uncovered reliability problems while working to integrate the speed detector with new digital radios and automated number plate recognition (ANPR) systems. The same officials had already known about the possibility for radio frequency interference. A 2002 ACPO test registered interference any time a radio or cell phone was used within six-and-a-half feet of the VASCAR machine. "There is a potential risk of interference to Traffic Law Enforcement Devices (TLED) such as VASCAR from Airwave Radios and GSM phones," a Devon and Cornwall Constabulary memo dated August 19, 2008 explained. "Officers should not operate a TLED from within a vehicle in the presence of a GSM phone or Airwave radio that is switched on, unless a 'Transmit Inhibit' system has been enabled. Failure to do so may compromise the integrity of any relevant prosecutions." Now Scottish officials fear the possibility that lawyers will seize upon the unreliability of the technology to undermine past prosecutions and force refunds.

I remember a case from the paper quite a few years ago in which a Skoda driver was timed at around 100mph, and contended in court, amid general hilarity, that his car couldn't go that fast.

I don't remember whether he got away with it - magistrates can be kind when sufficiently amused - but a good example of the Skoda Estelle 130 in proper tune could certainly do 100 four up, and a fairly mildly tweaked one could nudge 120.

The fact that most examples in this country weren't in proper tune, combined with all the ignorant Jasper Carrott hee-hawing 'Skoda jokes', made people in general underrate the car's real capacity. To the great advantage of the eccentrics who liked the thing.

I am going to call your skoda estelle "robin hood". Like all good folk or fairy tales, the passage of time has exagerated its fine points, giving it mystic abilities even, yet starting to forget its bad deeds.

100mph 4 up in an estelle - even a 130, is the stuff of marvel comics.
Driver to prove car can't do recorded speed - Lud
I'm not really exaggerating AE, honestly. Or hardly.

A good example in proper tune would go over a hundred on a motorway downslope and hold a hundred or a bit more on the flat until it came to a serious upslope. Like a 1.2 Punto without the refinement or gross understeer. A heavy load in the car lowered it a bit, especially at the front, and noticeably improved the aerodynamics, although what in the context one must laughingly call acceleration, er, suffered still further. It wasn't quite delivering full power in top at that speed - a whisker over 4,000 rpm - and continued to gather speed with a willing whoop and holler when you floored it down a slight incline. But a really steep motorway hill, with a bad head wind, could spoil the fun a bit sometimes.

It's all in the driving really, and I suppose flat-out motoring in a cheap rear-engined Czech car isn't everyone's cup of tea. Perhaps it wouldn't even be mine now. But it used to be... you're quite sensible about most things but here I am afraid you have been influenced by the tiresome Carrott, and perhaps by a brush with a dead-rough Estelle or two. There were certainly lots about, but even the rough ones I had went better than most people would have expected. Made a hell of a lot of Surrey Beemers and Audis look silly, and uphill too.

Momentum, AE, momentum...

I watched a couple of policemen demonstrating their VASCAR at an open day at Goodwood once. 900 and 1000cc bikes were coming round a corner and accelerating hard up the straight.
Plod explained that he pressed button A when the bike came into view then button B (or whatever) when the bike passed him.
"Look" he said, "That last one was doing 80mph. I bet he would swear blind that he was doing 120"
I said the bike probably was. Plod gave me a funny look.
I explained that the bike might have come around the corner at 40 and accelerated to 120 - this would make his average speed 80mph.
"Sorry" he said. "He was only doing 80. It says so here."

Worrying.

My daughter had one, and I would say I kept it in good tune, but I think this would be 'pushing it'. Maybe, downhill, with a good tailwind.

Worrying indeed as VASCAR stands for Visual Average Speed Computer and Recorder , the emphasis being on Average!

Vascar checked out by scientists and found OK. The ban imposed in Scotland lifted by ACPO.

Their speed measuring equipment is meant to be accurate.


I was caught speeding (my one and only time) in a 60 mph limit by a police officer in car parked in a road to the side and was given a fixed penalty notice. He had timed me between a roadside tree and a field gate as I approached the side road, using a manually operated electronic form of stop watch mounted on the dash of his car. The device proceeded to calculate my average speed to two places of decimals!

In the mid 1960's I worked with a lad who was prosecuted for doing 42 mph in a 30 zone on his motorbike.

The case was that the police had a speed trap on the far side of a set of traffic lights and clocked him when he set off from a red light. He was able to prove, from manufacturer's data that his bike could not have reached 42 mph from rest to the speed trap.

In court, the Inspector prosecuting, said that even if the bike had not been doing 42 mph, it must have been speeding and my collegue was convicted.

The above event was over 40 years ago and the injustice of it still rankles with me.

Knock Hill is not representative of the the road at Corpach on the A830 which I know well. The outcome of the Knock Hill test will not stand in court. Even a test at Machrihanish Campbeltown, airfield which can be made available would most probably prove the car can do 100mph but many measurements would be needed to prove the car could not reach that speed in the distance travelled on the A830. Engineers will be needed to ensure the car has not been remapped to slow it down and a whole load of stuff including fuel samples, that is going to cost seriuos money. Machrihanish airfield main runway is not totally flat but a run in either direction will resolve the average max speed. I suspect it will come out at way over 100 mph. Regards Peter

I doubt if it will come to this.

Remember the driver's lawyer that 'proved' the throttle could be affected by external signals, thus explaining why they drove their automatic into whatever it was they hit!
Driver to prove car can't do recorded speed - Stuartli
This isn't the first time such an attempt has been made. IIRC at least one motorist succeeded in proving his car couldn't reach the alleged speed.
