Good advice from Todd. Sometimes these incidents can't be avoided (like the parking thing) but others can. If I see somebody starting to drive aggressively behind me, I just get the hell outta the way and let them get as far away as possible. I drive the 911 the same way I would drive a motorcycle - very cautiously around other vehicles. Sometimes it is fun though. Seems like women in minivans just have this genetic urge to try to accelerate faster than 911s when in traffic. One time I was coming from a traffic light on a 55MPH highway. The soccer mom next to me just planted her foot to the floor. I casually stayed with her but back a few car lengths to kinda see how fast she would go. She eventually hit 90MPH in this 55MPH zone!!!!! I almost had to pull over, my daughter and I were laughing so hard.
