Teaching people the unusual rules of the road would make driving a little less frustrating in busy centres.
For instance, everybody knows that it is legal to make a right turn on a red light. However, it seems few people realize it is fine to hang a left on red from a two-way street into a one-way street.
If there are no vehicles approaching from your right on the green it’s perfectly safe and efficient and reduces lengthy backups.
What drives-u-crazy?
