I can certainly understand bad drivers... they make me angry too.
One reason that people flash their lights at you may be because of your headlights.
Some cars today have overly bright headlights and they "appear" to be highbeams when they are not.
When I got my new car, I noticed that some people were flashing me on the regular setting. It can be as simple as this. When they do that I just flash them back...so they can SEE the real difference!
