Sometimes I drive 65mph, sometimes 80+mph, and occasionally 100+mph, the point? I drive fast when I want to, but not to race people. If I get tail gated, I just move the right, and let the idiot pass me. I didn't buy the car to race people, I bought the car for the joy of driving a BMW.
Occasionally, for the fun of it, I tail gate the car in front of me for a while, if they yield, I speed up and pass them, if they speed up, I slow down and watch the idiot moving faster and faster away from me, and put a smile on my face.
