I've seen this before. We can leave this up as a video of why we should not be driving our cars in excessive speed on public roads. Notice that they are passing cars coming the other way which means that the road is not closed or much of a back road. Imagine if a car had been coming the other way, or if that happened on a blind corner, that could have been very dangerous for other drivers. Don't get me wrong, I would love to go for a burn in my car and there are some things I am not proud of in the past, but we really need to strive that this sort of driving should be done on a track. Our cars are just too fast where we can get into trouble before you know it. Public roads have animals, gravel, pot holes, fluids, debris, inattentive drivers, among other things to be 100% confident that nothing will happen. I'm sure the drivers in this video thought nothing would happen and if it happened to them, I'm sure it could happen to anyone of us.
I don't like saying this sort of thing because going out to a back road and enjoying your car is exciting and fun and I feel like a parent saying this. Just try to get to a track whenever possible. What happened to these guys is the best outcome that could have happened for having an accident. (I'm not saying I'm glad they crashed, I am saying they are lucky no one else was involved.)
Anyway, with a little elbow grease, I'm sure that'll buff out.
