A week ago we were on a 400km drive. In that time there were 2 completely separate fatal accidents along our route. Both were caused by excessive speeding. Not just 10 or 20km over the speed limit but excessive. One was figured to be going more than double the speed limit. One of the assholes took another innocent driver with them. I have changed by opinion on speed cameras and red light cameras because even on city streets so many drivers think that whatever speed they want to do is ok and they don't give a rat's ass about anyone else on the road. Unless drivers improve, I think every technological means necessary should be used to tackle them.
