NASCAR driver says his video-game-like move could've been 'really stupid'

"Wall riding" has long been a tactic in racing video games, where players -- without fear of sustaining real-life damage -- accelerate recklessly into turns, hugging the wall as they carry speed into the next straightaway. Hardcore sim racers typically complain that this maneuver is too unrealistic, but Chastain proved last weekend that it can be done in real life, though even he can't believe he pulled it off.
