Cars (2006)

Other mistake: After the first race, in the scene where Lightning is rushing out on the stage thinking he is the winner, loads of confetti is shot out when the King and Chick Hicks gets onto the stage. The confetti is then falling down, but not a single flake hits any of the cars. However, in the following shots, you can see plenty of it on the stage underneath the cars, even though they haven't moved.

Lightning McQueen: Look, Doc said when I finish, I could go. That was the deal.
Doc Hudson: The deal was you fix the road, not make it worse. Now, scrape it off! Start over again.
Lightning McQueen: Hey. Look, grandpa, I'm not a bulldozer. I'm a race car.
Doc Hudson: Hohoho. Is that right? Then, why don't we just have a little race - me and you?
Sally: What?
Lightning McQueen: Hohoho. Me and you? Is that a joke?
Doc Hudson: If you win, you go and I fix the road. If I win, you do the road my way.
Sheriff: Doc, what're you doing?
Lightning McQueen: Hahaha. I don't mean to be rude here Doc, but you probably go 0-60 in like, what? 3.5 years?
Doc Hudson: Then I reckon you ain't got nothing to worry about.
Lightning McQueen: You know what, old timer? That's a wonderful idea. Let's race.

Trivia: The company that offers work to Lightning McQueen is called Dinoco. Dinoco is the name of the gas station that Andy stops at on his way to Pizza Planet in Toy Story.

Question: Can someone explain the mechanics (and physics) of how Doc's advice to "Turn right to go left" helps with McQueen's drifting?
