Looking back at this, looks like it's just a prank. He did not actually turn his lambo into a controller, would require much more work. And the guy is rich, but not to the extent of sacrificing a lambo to do this. Still, this is pretty fun to see. Just playing Forza *inside* a real lambo would add such a tremendous amount of realism to my gaming sessions!
BTW, guy is franco-belgian, and got rich by selling the 3D graphics company he created after graduating to Sony in order to concentrate on his real passion, you guessed it: cars.
