Don't forget that we ALL think we're above average drivers.... that's the one thing that virtually every person in the driving world has in common! I do speed, but I certainly don't agree with the old BS "everybody does it".... my mum certainly doesn't and neither does my dad!
The rules have to encompass everyone, including the stupid, senile, frail old codgers that I wouldn't trust doing 70 on a duel carriageway, let alone 100.
Like I said, I speed... but if I get caught then it's my fault. I may not agree with some of the speed limits in this country but that doesn't mean I should decide which laws I follow and which I don't!
