As for drunk driving, I don't know why people haven't figured that out yet...the US has the toughest DD laws in the world

1) We have one of the higher legal limits out there (ignoring Islamic countries, which often have none). The fact that we are allowed to "have a few" and then drive home has astonished more than one foreigner I've come across in my short life.
