EV Silence Triggers Motion Sickness for Passengers

Electric vehicles (EVs) are increasingly being associated with motion sickness among passengers, a phenomenon linked to their advanced engineering. The cathedral-like silence of EVs causes a sensory mismatch. Passengers' brains struggle as their eyes perceive motion, but their ears do not detect the expected engine noise or vibrations from acceleration and deceleration. This discrepancy is a primary cause of travel sickness.

Further exacerbating the issue are characteristics unique to EVs. Regenerative braking, which slows the vehicle upon lifting off the accelerator, can be abrupt and unexpected for passengers. Additionally, the immediate and linear torque delivery in EVs can make acceleration feel more abrupt than in traditional combustion engine cars, intensifying passenger discomfort.

While drivers typically avoid motion sickness due to their active control and anticipation of movements, passengers are more susceptible. Emerging research and anecdotal evidence support this link, prompting some manufacturers to introduce solutions. Features such as motion sickness relief modes, which adjust acceleration and braking, and the use of artificial engine sounds are being implemented to improve the passenger experience.
