I was riding the train into SF and got talking with a guy who's over here on a couple or three weeks' vacation, a schoolteacher from Amsterdam. The reason he was in a pit like Sunnyvale was he was helping his sister move. Anyway, we got talking about biking, and according to him, the car drivers in Amsterdam are really aggro, and biking is much more dangerous there than here! He said American car drivers (at least we must assume in the Bay Area) are on the whole incredibly polite and considerate of bikes and peds compared to where he lives. Needless to say I was absolutely astonished at this news, but he seemed to know what he was talking about.
