I think that we would like that to be true & believe that it is true, but I have not seen any evidence.Anyone with a basic understanding of human psychology can see that the type of person to decide to break the law in the first case is more likely to decide to break it in the second as well.
Every single car driver breaks the speed limit every single time they drive!
I'll explain my reasoning - the limit is say 20mph, the only way not to exceed that would be to drive at say 80-90% of that limit, as bumps/potholes etc cause the throttle/vehicle to change speed by a few mph. So 20.1mph is breaking the law, the convention however is that you will not be prosecuted until you exceed 20mph plus.
So each driver accepts that he does not need to watch his speed to the last decimal & instead can watch the road & reduce his speed when he next looks at the speedometer.
But having spotted that the speed may be over the limit behaviour is not altered to drive at say 80% of the limit in the future, because the majority drive at 100% plus.
I think we all decide what laws to follow, in the hope that others will conform.
I certainly have wished to drive through red lights, when stuck behind a smoke belching exhaust, but never would, not because I do not have a number plate & so the chances of being caught are slight, but because I wish to set an obvious example of abiding by the law.
Perhaps in the forlorn hope that drivers will also not break the law, such as overtaking me on solid white lines, when if the meet an oncoming car, rather than have a head on crash they will instead take me out.
