I think that the P car gets some folks jealous. The only thing you have done wrong is own and drive a P car. Some others may think they can never afford a P car so they take it out on you so my thinking is don't fall for their bad behavior and just get out of there asap as if you a motorcycle.
I bought a dashcam for my Miata because many just don't see low cars. Especially half ton trucks. I bought one for $100 canadian or about $75 us.
