Help me understand these "crash" videos?

I can't speak for new high performance stuff, but I blame good old fashion physics. When you're at the track, the surface is prepped and your slicks are evenly warmed up right? Ever see a car burn out with one slick that didn't get water on it? I've seen ugly hooks to one side...

now think about the random crap on an ordinary street. Better yet all the water from air conditioners that gets laid down at intersections. Be careful when you decide to launch is all im sayin' ....
