The first video was bulllllshit. That should've never been lined up like that. What a retarded move... I bet the guy that hit everyone had a fun time buying all those cars.
The second video is old - but fairly obvious as to what happened. Foot went to floor when he tried to touch the brakes and rather than doing something smart he panicked and just pointed it at the tire barrier in hopes that it'd stop.... I guess he missed the 2 or 3 foot kicker before the barrier when he decided to point it there and that's what got the awesome airtime. My favorite part is that he takes the keys out of the ignition before he gets out of the car....
