Not to get too technical, but:
The forces on a turning car are complex. When you are in a car turning,
you feel like you're being pushed toward the outside of the turn. People refer
to this as the centrifugal force, a term that is a unfortunate because there
isn't any force pushing you outward. Centrifugal force is what physicists call a
pseudo or a fictitious force, because it doesn't really exist.
The force that makes a car turn is called the centripetal force. Centripetal
literally means "toward the center"...
A race car doesn't have a string making it turn. The tires have to do that job,
and they do it by exerting force toward the center of the turn. Engineers talk
about lateral force. The lateral force is perpendicular to the direction the car
is going at any moment.
The size of the centripetal force is given by multiplying the mass of the car
by the speed of the car squared, and then dividing by the radius of the turn.

FWIW, when the centripetal force acting on a body traveling in a circular
path is "cut," goes to zero, the body continues in motion in a straight line
tangential to the former circular path, and not radially as might be guessed.
