Sounds like there's a lot of angry/road rage drivers in the US.
In the short time I have had my Z I have noticed much of the opposite where I live. People stay out of my way, give way when not necessary and give me preference when in 50/50 situations. Almost like a level of respect for the car as opposed to the jealous/arrogant approach.
On the chick magnet front, most girls I've spoken too don't even have any idea what a 370z is....but they love it when they see it
.
In general I've found people take it different ways. Most fall in love with the car and think "wow, nice work or having an amazing ride" others get a case of tall poppy syndrone and get jealous, thinking "who does this young guy think he is driving something like that". Happens from time to time, especially coming from a working class town.
