I love the anxiety caused in motorists when they are confronted with the 2 mutually exclusive facts that:

1. They are driving next to a bike and must speed up to pass the bike, and
2. There is a stopped car in front of them and they are going to have to stop.

Actually, one thing I love more than that anxiety is the sight in my peripheral vision of the car's hood dipping while braking as I maintain my speed.
