Electric vehicles may increase passenger motion sickness

Research and medical experts suggest that electric vehicles (EVs) may increase the risk of motion sickness, known as kinetosis, for some passengers. This discomfort is primarily caused by a ‘neural mismatch,’ where the brain receives conflicting information between what the inner ear senses and what the eyes perceive.

Several specific characteristics of electric vehicles contribute to this phenomenon. The quietness of the electric motor provides fewer auditory cues for passengers to anticipate acceleration compared to internal combustion engines. Additionally, the rapid response of the accelerator and the use of regenerative braking can cause sudden changes in speed and deceleration that may be difficult for the body to adjust to.

To mitigate these symptoms, experts recommend that passengers avoid using mobile devices or reading, as focusing on a stable screen while the body moves intensifies the sensory conflict. Instead, passengers should look at the road ahead or a distant point to help their vision align with the vehicle's movement. Sitting in the front seat is also advised to allow for better anticipation of the vehicle's motion.
