OMG - that's some weird kind of driving

One false move and the driver is dead (without helmet and rollcage).
BTW: The comparison is somewhat unfair - the Ruf is apparently on street tires and the (heavily tuned) virtual Bimmer drives on slicks I guess (the speed would be okay for the normal 120 i if it where km/h, but it's mph here!).
edit: Just read in the movie credits that the GT 4 section was timestretched to match the Ruf's speed. My personal hint for GT 4 owners: Get the Ruf "yellow bird", drive it with sports tires soft or race tires hard on the ring and try to keep that beast on the track - it's a real competition!
