Remember how you have to be an idiot to go fast? This driver was suffering from electrical problems, so he unplugged and re-plugged his steering wheel at speed, and he stays full throttle. I think that qualifies as idiotic.
Watching this Formula Renault driver come up on the next corner with his steering wheel in his hands (not unlike the Caterham driver putting his gloves on mid-race) proves the maxim about racing drivers: either they have really big balls, or really small brains.
