Two things that really annoyed me on my drive home from the dog walk today:
1. When I have my cruise control set and a few miles above the speed limit and people still pass me.
2. Unreadable/poor use of fonts. There is a van always parked at this one business and every day when I pass it, I try to read what it says on it. The font is like red surrounded with white surrounded with black and I can never make out what it says. Poor use of font and font colors bothers me. It would be perfectly readable if it was black helvetica.
