I get the occasional wave but no invitations to race. But I don't really look for that kind of stuff, so maybe it's happening and I just don't notice.
If someone is trying to goad me into a race, they are wasting their time. I have a pretty good idea of what the car can do and don't need to prove it anyone. And it wouldn't bother me a bit if I had the slowest car in town - the Z is plenty fast for me.
