>>My concern was with the limit of 80mph. That is WAY TOO FAST. The only reason I can see a teen needing to go 80mph is in order to pass and if they have to go 80, then they shouldn't be passing anyway because chances are a teen cannot handle a car going 80mph.

>So 80 mph isn't the only option. - Anyway, 80 miles is about 129 km. - about twice as fast as I deem reasonably safe. I should admit, though, that over here, the roads, and traffic conditions, don't make it safe to go very fast.

On the major highways here (the 401 for instance) the speed limit is 100kph, but most people regularly drive between 110 and 120. That means that passing requires 130 easily. In fact you'll see people just driving in the passing lane at that speed. I've heard a lot of people refer to it as the fast lane (which it isn't - it's just the passing lane).
