Factual error: When Ding Bell is passing the truck, his car downshifts then shifts into a higher gear after passing the truck. Ding never took his hands off the wheel. This is in a VW Bug. These all had manual transmissions when this was filmed. He would have had to manually shift the gears to have the car change gears, but he kept steering with two hands on the wheel.
