1st vid - total fucking tards. If I saw someone in a MKIII driving like that, I would publicly beat them over the head with the patented 'Supra Stick' hood rod, while video taping it for SM's viewing pleasure.
2nd vid - It's called Wangan Racing. I have done it, and yes, it is the single biggest adrenaline rush of your life.
I would not think about doing it ever again though. I was 18, and stupid as hell. It's one thing when I want to get my jollies off - it is something else ENTIRELY when I endanger everyone on I4 doing it.
At the time, I thought it was badass. Looking back (amazing what clarity only 6 years can give you) I realize it would have only taken ONE woman gakking on her cell phone, not paying attention, to cut in front of me, and I wouldn't be here right now. I see it all the time with women in SUVs, and that's just at 35mph. How much more dangerous is that at 135mph?
Think about that. Let that sink in. For a few moments of adrenaline, I gambled with my life. Is that a gamble you are willing to risk?
I know I'm not.
