1. Red indicator signals on cars, especially when they're acting as both brake and indicator. Amber only please.

2. Folks who don't use what's easily available to them. For example, the dumb folks out there that don't use Bluetooth in their Bluetooth-equipped Bimmers. Or the folks using a Garmin attached on top of their 7er.

3. The uppity, self-righteous old ladies of rural Virginia, that flash their headlights in anger and make rude gestures if you so much as drive 0,0005mph over the speed limit. One of them actually went to the trouble of blocking my way once and telling me to slow down. As payback, I enjoy overtaking them on one-lane highways.

4. Improper grammar, especially on road signs. It's supposed to be " Reduce speed ahead" without the extra "d".

5. Multi-lane rural divided highways without controlled access.
