I'll give it to you that we all make generalizations... rationally or not. And most of the time they are driven by conscious or subconscious biases.
I will say that I get harassed by 350Zs a lot... but I try to avoid generalizing the car and its drivers because it's a lot like blaming a deadly shooting on the gun. Did the gun kill the victim? No, the criminal that shot the gun did... And whether some young douchebag with enough money to buy a used sports car chooses to be a douche in a Z or a Mustang is really up to chance.
The fact is I encounter douchebag drivers on a daily basis, and sometimes they are in a Z, sometimes a Mustang, BMW, etc... but a douchebag is a douchebag and it doesn't matter what car they drive. If a douchebag Mustang driver traded his car in on a Z that's not going to change how he drives... however it might change how he is perceived by his own kind... just sayin'.
