Be careful of speed traps on the 401 just before the Ont-Quebec border (on the Ontario side).

The problem is that these speeding laws are advertised as being saving lives. IMHO, it's agressive driving that causes and not just speed. There's being countless times when people are tail-gating, and weaving in/out of tight traffic when they have no business doing so and the police are not around. Hiding behind the bushes catching those doing 20km/h above the limit does not save lives; it's just a tax grab. To save lives, the police need vigilance in patrolling roads and monitoring driving behaviour.
