Some of them can be cool about cars. Back around 1978, I was driving a 73 Cuda. It had a 383 in it, and I put a 2x4 intake on it, but I couldn't get it to run right. One night, when I was at the local motor-head gathering place (A large unused parking lot), I was talking about it with a friend of mine, who was a really good mechanic. He took a look at it for me, made a few adjustments to the linkages, and said "Try it now". Well, the parking lot had two entrances, one on each end, and I didn't want to do anything in the lot because there were people and cars all over the place, so I pulled out onto the road, and floored it. It burned rubber from the one entrance to the other, which was several hundred feet away, where I had to shut it down in order to make it back into the other entrance. When I pulled into the other entrance, I saw the city cop that had been sitting there talking to one of my friends. I pulled over, shut it off, got out, and waited for the inevitable. He walked over to me and said "Runs really good, doesn't it?" I replied "Yeah, I just got it adjusted right". He laughed, and told me to do it outside of city limits from now on, and then went back to talking to my friend. I gained a lot of respect for him that night, because although he could have been a @#$&^# and arrested me, he chose to teach me a lesson in a different way. I never did do another burnout within city limits, ever again.
