OK. Let's get down to brass tacks. The US has a population of over 300 million. Canada has a population of 30 million in an area twice the size of the US. I'm going to take a wild stab at it here, but it's my guess that our ratio of traffic cops to km (or mile, take your pick) of road is going to be waaaay more favourable.
You see, while you Americans can only use your Pantera to crawl along in endless stop-and-go traffic jams at the Traffic Gestapo-enforced pedestrian speed limit in a vain attempt to impress the girls, us Canadians get to tear up some pavement and regularly drive our cars the way they were intended to be driven.
