I had one riding my butt on the highway a few months ago, so I "separated" from him by way of 4th gear. Surprisingly, he hung with me for a lot longer than I thought.
I got a call from my fiance who works as a police dispatcher, and she asked me "Were you just racing a Pontiac on the interstate?" I was SO worried, but it turns out he's one of her coworker's boyfriends that knows I drive the 370z. He called her to say how fast our "little car is".
