Yeah actually that was a bummer but the camera man wanted to go. Bit ticked at the wall thing, I could have braked but that would have resulted in about .5 of a second without fluent drift. Trust me, that would have been missed, then again I did end up with about 1 second without slide. Meh to complicated for my liking.
Nice little vid, I was drifting there myself not long ago in the Dukes, it's the best car for it, easily will slide all the way up (and indeed down) the entire ramp with some nifty driving.
