I’m not a motorsport person, but I AM a videogame person.
A NASCAR driver (Ross Chastain) just did a Mariocart wall-ride to come from way behind and put himself into the championship. It’s completely bananas.
The principle here is pretty simple: speed is limited by your traction. The rest of the drivers were held to their track by their tires (and aero downforce) alone. By putting his car against the outer wall, Chastain was able to floor it because the wall itself kept him on the track — though obviously at significant cost to the right side of the car.
Here’s coverage; in a postrace interview, Chastain explicitly cites using the tactic in the GameCube NASCAR game as a kid, and figuring it was worth a hail-mary move given the circumstances.
Here’s a longer video showing the move from a variety of angles — this is probably better, because from several you can see how WILDLY faster he was moving in the crucial moments.
