Well that's plainly garbage ScoTTy. Obviously they have to take an average when investigating an accident, but to say the margin is narrow is pure b*llox. Mini Mk1 with drum brakes all round can stop roughly in the same distance as an RS4? I don't think so, you'd be looking at 50% diffrence at least and that's not even taking into account ABS, state of the tyres (crappy old car is far more likely to have sh*te tyres). I agree that brand new cars will be closer, but that's not what Eeef was saying.
