I dont understand why people would be pissed at your car? Now on the other hand I can understand it if you reved loud and burned out. I have been attending street rod events for close to 30 years now, and I havent ever seen anyone get pissed at someone over their build. Now what the owner does in their car is another story. From my experience, if you have regard for other people, and have respect for them and not act like an child, all is well.
