What makes drift cars go sideways like that on concrete?

May be...

It's basically a donut that the driver is turning out of to keep it going somewhat straight. The rear wheels are spinning so there is no traction but the forward motion of the car is kicking it to the side because the brakes applied to the front are not allowing the rear to go forward.

I'm not very mechanically inclined so if you could give me the "drift cars for dummies" version, I'd be more apt to understand it, thanks.apartment hong kong serviced short stay
