Unblemished driving record no more :-(

Last Sunday, I headed up to Mt. Aso with a couple of friends. Mt. Aso is (I believe -- the informational placards were in Japanese) the largest crater on the planet as well as the most active volcano in Japan. It's pretty cool-looking. Anyhow, I was driving and I rear-ended someone. It was stop and go traffic, I scratched my eye, and hit the guy at a whopping 2mph. Totally my fault, but as accidents go, it was about as minor as possible. The other guy has a significant dent in his bumper, that doesn't quite seem to look like the front end of my car if you know what I mean, but there's not really anything I can do about it. Everything's covered by insurance. My rates will go up next year if I stay in Japan, but only $100 a year. That's scarcely any incentive not to hit people I don't like.
