I dont think its so much a matter of doing stupid **** on the street. There's an awful amount of canyons and roads on this planet that are secluded enough for one to have spirited fun. I'm not talking reckless stupidity, although its a thin-line, I'm talking about fun. In this case, I think it was just a matter of bad-choice, bad road. This section of Mulholland is known. So known, that a camera crew sets up on weekends to capture the fame and fails. Not everyone knows this, since not everyone is from Los Angeles....on a race track where there isn't an opposing lane of traffic.
On the street it's just dumbsauce.
