Which of the following factors does NOT affect cornering?

The selection of the option indicating that weather conditions do not affect cornering is not accurate. In fact, weather conditions play a significant role in cornering because they can alter the grip and traction of the road surface. For example, rain or snow can reduce friction, making it more challenging to navigate a turn safely.

The factors that do affect cornering include the condition of the vehicle, speed, and steering input. The condition of the vehicle, such as tire health, suspension, and brakes, directly influences the vehicle's ability to handle turns. Speed is critical as taking a corner too fast can lead to a loss of control, impacting the vehicle’s stability. Steering input is also vital because the way the driver maneuvers the steering wheel determines the path and angle at which the vehicle takes a corner.

Overall, each of these elements is integral to maintaining control while cornering, while the impact of weather should not be underestimated.
