How does the black car do that 2nd spin? (6:30)
The back of the car totally reverses momentum !
Where does this force come from?
I know nothing about racing theory, but here is what I've come up with.
The car is initially oversteering with the back sliding left. So the driver countersteers and cuts the wheel all the way left.
It seems the front wheel finally gets traction the moment it touches the curb (different surface?)
The driver has corrected the oversteer, and the rear tires find traction.
At that point, the car gets jerked straight (since the front wheels are still turned left), instead of continuing sideways.
This inertia shift tugs the back of the car to the right since the car is straightening.
However, at that moment, the car now finds itself on wet grass, which might as well be ice.
So the back continues to swing right like a pendulum, and ultimately the car does a 180.
If the grass wasn’t there, do you think the car would have made it through the turn without spinning around ?
