Why? It should be good sport to pass them on the winding roads with your Z!
Hah! I do that alot, but what is really.. funny.. is this INSISTANCE on the part of many SUV drivers to actually try and RACE me! On the highway no less! Its hilarious. I think that the low end grunt and takeoff that many SUV's are geared for, fools the drivers into thinking their vehicles are faster than they really are.
Back when I used to be a bad man, I would indulge them, and allow them to try and follow me onto my favorite 70 MPH curve.. oh, did I say 70? I meant is was a 50 MPH curve, which my car could easily take at 70, 80 if I was in a hurry. Seeing one of those beasts tip onto two wheels was enough to stop me from doing that again, I mean, it wouldn't be my fault, but I would still feel terrible if something awful happened.
