I've had several british friends tell me that if they pass cars in America like they do back home (say, within a foot with both cars traveling at 25-30mph), American drivers will go ballistic at them and can't believe at "how dangerous they are driving". The difference is that they have much better training and know that they can pass safely.
Come to Ireland and leave the motorway network for our country roads, we pass within inches of bushes on one side and cars on other at 80 to 100km/h while being blinded by idiots misusing fog lights and reflections of perpetualy wet roads. These "roads" resemble twisty tunnels thru trees :D
