What effect does driving faster than traffic flow have on fatigue?

Driving faster than the flow of traffic typically creates tension and stress for the driver. When a person exceeds the speed of surrounding vehicles, the driver often feels compelled to remain vigilant and reactive due to the higher risks involved, including potential collisions and the need for quick decision-making. This continuous state of alertness can lead to mental and physical fatigue, as the driver is unable to relax and may experience anxiety about their speed and the behavior of other road users.

Additionally, driving at speeds that are inconsistent with surrounding traffic can also contribute to feelings of isolation and frustration, as the driver may encounter more aggressive behavior from others or face an increased likelihood of road rage incidents. All of these factors combine to wear down mental resources, resulting in heightened fatigue over time.
