My friend live right next to a highway ( 80 km/h ) a little further down the road the police often set up shop, so they did last week and captured a guy doing 185 km/h.
This is where i think "guy should never be allowed to operate any form of motor-vehicle"
We just got back from a trip to Seattle, Vancouver and Calgary. The number of drivers we saw hogging the overtaking lanes, despite the abundance of warning signs, was a joke.
They sit there because they are ignorant of the rules and they don't get caught doing it. If there were more visible police vehicles enforcing the rules, then behaviour will definitely change.
