You've got a massive semi truck and a frozen, mostly wide open, parking lot so what do you do next? Well, you go absolutely nuts and try out some sweet drifts. Granted, one wrong move and you could wind up with some serious semi on semi crashing action. Personally, think the first pass he makes is far superior to the second. Regardless, you need to have some serious skills to pull this off without everything going horribly, horribly wrong.
