If you want to see car control, look no further.
This was reportedly Fernando Alonso in some kind of little kart track from who knows when.
I'm somewhat convinced this is indeed the two-time world champ because 1) the helmets match, 2) Alonso karts reasonably often, and 3) the way he holds a car sideways, even linking turns all the way through at angle, is absolutely incredible.
UPDATE: It's not Nando! The excellent people at Karting1News turned up the original video from 2012 now at the top of the post. It's Colombian driver Felipe Merjech at the wheel. He might not have any F1 seat, but maybe he should.
