I think the road safety campaigns have created a good portion of drivers that think doing 73 in a 80 kph zone (or say 91 in a 100 kph zone) ......... is just the ducks nuts and look how safe I am driving - in certain circumstances this could well be the case
But, that same person is the one that I think causes bad decisons from others and accidents
Usually that person when they get to a passing lane will speed up to 10 to 20 k over the speed limit - they should slow down and let everyone pass !
they then will decrease to a turtle at the end of the overtaking lane where no one can then pass
