What's the usual mph/rpm ratio?

My friends Volkswagen Tiguan 2.0 Auto Diesel does 60mph at 2000 rpm in top gear on a flat road.

I think this is about 500rpm too much. There is no change in rpm when switching the gear change from normal to sport at 60 mph.

If the engine is running too fast obviously it uses more fuel and increases wear. Is this normal or is there anything that can be done, please?

30mph per 1,000rpm might be about right to give a sensible top gear for towing. But I'd have thought (as you do) more like 35mph per 1,000). Maybe it's not getting into top (7th) gear of the DSG.

Getting onto a motorway from a slip road

I have passed my driving three months ago and I'm now planning to go on a short trip using the motorway. I know slip roads are there to gain appropriate speed before joining a motorway's left hand lane....

What should we do if we break down in the live lane of a Smart motorway?

What should we do if we break down in the live lane of a Smart motorway? Should we ring 999, for example?

Should you give way on a slip road?

Surely on a slip road one should give way to a lane they want to enter? Braking for a vehicle wanting to join could cause an accident. One has to be aware what is legal as well as sensible.
