One of the things that struck me when I moved to Canada was the number of teenagers killed in car crashes. It seemed that a lot of people went to school with someone who died in a car crash. Back in the late 1970s and 80s few British teenagers had cars. But in Canada secondhand vehicles and petrol were cheap. In Scotland, or at least in Livingston, most folk knew someone from Craigshill High School who had been murdered or had murdered someone. A different world.
