Nice car, nice driving... well, talented driving, but extreemely stupid.
I'll admit that I've driven like that before. Back in high school I did a lot of stupid things that should have gotten me killed. Try driving like that after an eight ball... that will get the heart pumping. lol
The only thing I don't understand about that video is how he managed to organize all those cars to be parked on the interstate, at the same time.
Looking again at the video, I don't think what he did was THAT risky. It shows how derated the speeds on interstates can be. If you notice, he didn't ever go fast enough where he couldn't slow down given the amount of free space in front of him. The only luck he was relying on was that someone wouldn't suddenly swerve into his lane, which on most interestates is a reasonable assumption.
