For some reason, cars just have to pass bicycles, even if the bicycle is going the speed limit. I've tested this theory. When driving on a narrow 30 mph residential street near my house, if I come up behind a car and the car doesn't notice me, I can usually keep up with them because even though the limit is 30, traffic is usually in the 20-25 mph range.

Now, If I'm going the speed limit, a car in back of me accelarate from far away, catch up with me, honk, tailgate, and then make an unsafe pass every time.

Drivers are just jerks. I just take the lane and proceed as usual. But I do live in Miami, road rage capital of the world.
