What is the difference between high and low driving postures?

[DiQuinn]

The difference between high and low driving postures lies in the impact on visibility and the likelihood of causing driver fatigue. Below are the specific differences: Impact on visibility: A high seating position primarily affects driving visibility. When the seat is adjusted backward, the field of vision becomes broader, allowing easier observation of both sides of the driver's seat and a more expansive view ahead. However, if the posture is too far forward, the side visibility narrows, potentially creating hazards from side traffic or when changing lanes or overtaking. Likelihood of causing driver fatigue: A posture that is too forward and too high significantly affects the comfort of long-distance driving and increases driver fatigue. This is because the posture is not relaxed enough—it's like holding the steering wheel while driving, with legs bent to press the accelerator and brake, the waist positioned too forward, and the chest too close to the steering wheel. Over time, this can lead to back pain, leg cramps, and overall discomfort.
