++ to the numerous posters who noted that many drivers believe that riding on the road at all is somehow against the rules.

A few times a week I hear a local honking at a poor soul in a car with out-of-state plates, going slower than the speed limit, trying to find a good place to turn around. If they're behind me I play it really safe, even pull off the road, since they're usually flooring it to make up for the time the wayward tourist "cost" them.
We get a lot of tourists around here too. You have to be very careful around them, as they're likely to swerve or pull a u-turn suddenly and without looking. As in, "Oh -- there's the Lincoln Memorial" and cut across three lanes of traffic.
I've also noticed that tourists are disproportionately likely to be perturbed by bicycles in the street.
