Not the sort of thing you'd want to try on your first time drifting.
There are potentially some problems with drifting on mountain roads where one side is a sheer cliff. The potential for disaster will also increase when you decide to pass other cars while going sideways. You don't even need the cliff for that to be scary. But in the hands of a pro like Fredric Aasbo, even this 800-horsepower 2JZ-powered Scion FR-S can handle it without a problem. The whole thing was filmed by a GoPro attached to Aasbo's helmet.
It's certainly good driving, but the big crack in the windshield doesn't inspire huge amounts of confidence.
