So far this is the best site that I've been able to find so far about the bumper cars. They are also called skooters (no typo here) and dodgems. Those are the little mini cars that you see in amusement parks. You drive in a small arena where you bump into other cars.
I did see a few other sites, but they usually had one or two old photos and not much information. So this site has the most info and most [old] photos that I could find so far.
