The force doubles as it is directly proportional to the radius.
A shift in velocity can occur in either its magnitude (speed), its direction, or both. Even if the speed may be constant in uniform circular motion, there is always an accompanying acceleration since the direction of the velocity is continually changing.
Friction between the tyres and the road causes the centripetal force that causes the car to turn in a circular motion. If there isn't enough friction, the car will move in a curve with a larger radius and veer off the road.
