Probable Origin?

Today I was just sitting around thinking and I was thinking about where black folks got the idea to swing their cars(weave side to side from lane to lane). I remembered back to the days when I was a little kid and I remembered that when race cars in NASCAR and INDYCAR pick up tread while following the pace care, the swing from side to side. Now not saying that this is where tippin, swangin, or whatever came from, but it makes you wonder. Basically to me, it would be funny if one of the things that white people say is a big traffic nuisance came from the whitest and dare I say most redneck sport on the planet, stock car racing.
