Our current system of trying to change driver behaviour largely consists of traffic tickets, vehicle impoundment and driver's licence suspensions. They all rely on traffic policing to find and deal with those who don't follow the rules. How efficient is that?
When I worked on South Okanagan Highway Patrol, we were responsible for Highway 3 from the Manning Park works yard to the Rock Creek Canyon Bridge, Highway 5A from Princeton to the Okanagan Connector, Highway 3A from Keremeos to Kaleden and Highway 97 from the border at Osoyoos to Peachland. A typical dayshift consisted of 3 constables when we were all working.
What were a misbehaving driver's chances of being caught? Not that great.
