Rent a Cop
Where are the police when you see a traffic violation? Nowhere, that's where.
I propose the provincial/state governments create a course for the above average driver (someone with the maximum amount of merits on their license) to take to learn the basics of vehicle trafficing and violations.
Once the civilian has passed the course, s/he could be licenced in thier city and province/state and allowed to pull over and ticket other civilian offenders.
This system could be based on comission renumeration only so that the government pays a small percentage fee based on the ticket.
It's a win-win situation. The civilian makes money and the government makes more money as they are catching more motorists break the law, than they would have due to insufficient policing of traffic. Also, they could charge money for teaching the registered course.
Reward: I'd love to see this in effect anywhere! No reward needed at the streets would be safer for everyone!
