I must have some idea my friend. I've been driving 25 years without an accident and cycling for pretty much the same time on and off without accident either.
I haven't contributed much to this thread, but I want to point out that you're sounding a lot like one of the people in the film. The taxi driver who got upset when Gaz touched his car. He said something very similar, and yet it's quite clear from the film that he is a dangerous driver. I'm sure you've heard people talking about the stereotypical older driver who hasn't hit anyone, but leaves a wake of destruction behind them.
