What factor determines if a car will follow a driver's intended path?

The grip, or traction, of the tires is a crucial factor that determines whether a car will follow the driver’s intended path. Tire grip refers to the ability of the tires to maintain contact with the road and resist sliding or skidding, which is essential for control during maneuvers such as turning, accelerating, and braking. Good traction allows the tires to transfer the driver’s inputs into effective vehicle responses, ensuring that the car moves in the desired direction.

When driving, the friction between the tires and the road surface plays a vital role in how well the vehicle responds to steering inputs. If the tires have insufficient grip—due to factors like worn tread, incorrect tire pressure, or wet or icy road conditions—the car may not follow the intended path, which can lead to loss of control and potential accidents.

While the driver’s reflexes, the weight of the car, and the speed of the vehicle can influence handling, they ultimately depend on how well the tires grip the road. Therefore, enhancing tire grip through proper maintenance and choosing appropriate tires for the driving conditions will significantly improve a driver’s ability to control their vehicle effectively.
