All these are fine ideas (including thought but not mentioned hovercrafts)
On a side note, would love a German style legislation
1. While driving, you cannot have food, drink, phone or anything that would take your eyes off the road. Once in the car, it is meant for you to commute to the destination as fast and efficiently as possible.
2. Stricter exams. Canada is multicultural, however, that brings different driving styles, no uniformity and understanding of the law. Tougher driving rules and tests would make sure everyone understands "the right of way" or what to do when they reach a roundabout. It would also help with the 60kph on a 400 series highway.
3. Better traffic management. Implementing a minimum traffic management system could have tremendous impact (hopefully beneficial) to the am amount of traffic on the road. Improving gridlock and lowering the time people spend on the road would help the environment, lower travel time and allowing people to spend more time with family or recreational.
4. Better roads.This goes without saying. All the money going to bureaucrats, can be better used to improve the safety and status of our current roadways. 400 series has become a God forsaken land of some post war European country.
