it would just be hella people cruising down main streets. one car would start doing donuts at the intersection, and people would just get out of their cars & watch, since it would be stopping traffic anyways....basically, you'd hear police sirens coming and everyone would skat. the cops would only chase & pull over people who were swingin it or if they're driving off recklessly. most of the time when the cops show up they would basically be directing viewers away from the sideshow. then they passed a law saying that viewing or being caught in a sideshow would be punishable.
it usually would only take up an intersection and the streets leading into it.
