I find the best way to deal with said ***** is to jst sit there and shake ur head in total amazement at the **** driving, I won't under take someone as that is dangerous, I work in a small village 100 yards after the start of 30 zone when I'm reverseing out of the workshop if some **** comes round the corner and makes a meal of me being in the middle of the road, I simpley get out of the car walk over and say your in a 30 zone so stop driving like a ****, tbh it the older gen that's worst the young lads stick to the limit, about 4 hrs ago I woman in the village told my boss I was speeding ( load bass music) anyway about a week later she came thro the village so fast that when she had to stop for the school bus she locked up and almost took me and my boss out, the only way to deal with them is not to lower yourself to there standards
