I was talking about this in another thread and realized it could be its own. When I'm stopped at a light I check my mirrors rather frequently. When I see a car approaching from behind, I start pumping the hand break so the break light blinks at a pretty good pace. Since I started doing this I noticed that the approaching cager doesn't creep up nearly as close to me. Obviously it can't work on an incline but since I starting doing it, I did notice a difference in how cagers pull up on me. Didn't know if this might help someone else out...
