Which term describes the ability of a car to maintain a straight direction?

The ability of a car to maintain a straight direction is best described by the term "directional control." This concept encompasses how well a vehicle can be guided along a desired path, allowing it to travel in a straight line or maneuver effectively within the road's parameters. Good directional control means that the driver has a strong command over the vehicle's movements, particularly when it comes to responding to steering inputs and maintaining the intended trajectory without unnecessary deviation.

While stability control refers to systems designed to help prevent skidding and loss of traction, and steering precision denotes the accuracy with which a driver can steer a vehicle, these terms do not specifically address the overall ability to maintain a straight line. Similarly, path alignment, while related to how a vehicle sits on the road, does not fully encapsulate the broader concept of controlling the vehicle's direction. Thus, directional control is the most accurate term to describe the car's ability to maintain a straight direction.
