I have a theory as to why this happens so much with the Z. I think it's because of envy that leads to immediate competitiveness and emulation. You see, the Z is designed to perform well in every category. Even though it is not the absolute best in any particular category (except looks IMO) the sum of the parts literally dwarfs whatever those morons are driving while giving them some shred of hope that they can beat you at something.
People that mock are usually envious and the ones that want to pull right next to you and rev their engines are emulating what they perceive you are doing by simply existing. These are the ultimate compliments. Unfortunately folks with lower emotional intelligence give in to the impulses and go into caveman mode thereby losing control and acting like idiots. All you have to do is observe the egos running crazy and it will provide years and years of entertainment while keeping you safe. Don't let it get to you OP.
