A lot of people think that if obtaining a license is harder, the roads will be safer, but it's more an urban wisdom than science. If you take various numbers from around the world, you will notice there is no linear correlation between those two, especially when harder is pay more than you should and sit in class harder, instead of learn how to run a special stage on snow and ice harder. Also, in places where driving is a privilege, drivers tend to feel privileged. The sad truth is just that almost everywhere driving training simply sucks, with the well-known exception of Finland.
