So you have never *ever* drifted even .001 mph over the posted limit?

Why do you find it so hard to believe that someone could spend their
driving career remaining within the law? Were I to state, "I've never
burgled anyone's house", would you counter with, "So you have never
*ever* just nipped in through an open door and alf inched someone's
ceramic ashtray?" I see little difference.

And if he had once popped 0.001 mph over the speed limit would that devalue
his point about keeping to speed limits?

Seems a bit of an easy way out, saying 'everyone does it', as if that makes
it OK.

Lots of people assaulted each other in previous centuries, did the fact that
lots of people did it make it socially desirable?
