Seriously, this is why we can't have nice things.
The following video will start with a disclaimer that it was all professional drivers on closed roads, but it will become pretty obvious pretty quickly that this is a lie. Now, we've run a fair number of videos of street races, and of people going really fast on public roads. Some of them have shown a real effort to stay away from other motorists and not take any unnecessary risks, and some have not. This is one of the worst examples of the second type.
The fact that nobody was killed in the making of this video is something of a miracle. The speeds and distances at which they're passing are absurd, and their obsession with taking every blind corner at top speed is even worse. People like this ruin fast cars for everyone.
