I'm not 100% sure this guy was using launch control or just reached down to put the 911 in
idiot sport mode and disengage PSM (Please Save Me would have helped in this case). For that matter, other than knowing for sure if he was in launch mode, I'm not sure if sound would make this video better or worse? There's part of me that wants to see and hear the idiot behind the exhaust getting pelted with stones, but then the compassionate side of me kicks back in and I don't think I could bear to hear this Porsche punching that guardrail.
Launch control in a Porsche has many practical daily uses, but this isn't one of them. Seriously, isn't this what Mustangs are for? At least in today's world of always on media, this kind of idiocy is recorded and distributed for all others to learn from. Yeah, right.
UPDATE: So, I found this video and it has sound! Sounds like it was definitely a launch control failure. Please be forewarned. There is definitely some NSFW language in the video below.
As a parting thought, don't you just love how the kid on the right continues to video well after the guardrail gets the better of the Porsche?
