You guys who are saying he can't drive just made it obvious -- you have never driven a car on a racetrack.
And have likely never ridden shotgun either.
By the sound you can tell he's throttle steering out of many of the corners, sliding the tail out, controlling it, and giving the passenger a real thrill ride.
The fastest line around the track will sometimes take you over curbing on some corners, on some tracks.
The problem with the video is that the "journalist" in the passenger seat also has never driven a car at the edge, on a track, and therefore captured NONE of the driver's steering inputs. That is what is exciting about this... not just shooting straight out the front. jeez.
What you can tell from the video is that this car will slide the tail out and is controllable out of the corners (good) but we can't see how much correction the driver is doing to compensate.... knowing it's a BMW, it's probably a nice easy slide and countersteer.... would have been fun to watch that part.
