OMG, we have drivers from all over the world here. This semester alone I had to stop twice in one day to avoid a head-on with someone going the wrong direction, and another day, the same car crossed the solid white line in a curve into my lane, both close calls, but the second curve I was ready for her. Too bad she wasn't to my left where I have a rusting fender. The near head ons were actually on the same trip, one big assed dually on a one way street, the a large construction van in my left turning lane. I guess he decided since there is no left turn from his side of the street it was best to use the opposing left turn only lane. That one was close, because I was going to make the left behind him and, of course, no blinkey lights. After he turned into the wrong way of a one way ally, I finally got to wait for traffic to clear and go left :-\ And those were all Gringo's! I have to avoid an accident at least once a day now. It used to be about once a week.
