Driver error? Not even close. In the video, you can clearly see the driver has got both hands on the steering wheel, is looking ahead and apears to be in perfect health, except for the mental part of course. Both cars are also brand new, so mechanical problems are out of the question.
What's even funnier than the randomness of the crash is the driver's expression. After he pushes the Fiesta to the curb Corsa Killer here tosses a cigarette out the window with a sense of satisfaction and price. Give this guy a job as a stuntman and some Fords to aim at!
