There’s a growing concern that electric vehicles (EVs) may be more likely to induce car sickness in some individuals. This is due to the differences in sensory cues between EVs and conventional cars. For over a century, humans have become accustomed to the sounds and vibrations of traditional combustion engines, which provide subconscious cues that help our brains anticipate and prepare for movements such as acceleration, braking, and cornering. In contrast, EVs produce much less noise and vibration, making it more challenging for our brains to predict these movements.
As a result, the conflicting signals from our eyes, inner ear, and vestibular system can lead to motion sickness in some people. This phenomenon is similar to what astronauts experience when adjusting to zero gravity, where their brains need time to adapt to the new environment. EVs also have unique braking characteristics, relying heavily on regenerative braking, which can cause gentler but more frequent deceleration, potentially triggering motion sickness.
Other factors contributing to car sickness in EVs include the different vibration patterns of the seats, caused by the interaction between the car’s battery, magnetic field, and metal components. Additionally, the low-down torque of EVs, which enables rapid acceleration, may also be a contributing factor.
To mitigate car sickness in EVs, several strategies can be employed. Sitting in the front seat, closer to the car’s center of movement, can help, as well as paying attention to the driver’s actions to anticipate upcoming movements. Motion sickness medication and listening to white noise at 100Hz, which has been shown to be effective in Japanese studies, may also be helpful.
Car manufacturers like Jaguar Land Rover are exploring new interior design features, such as cooled seats, ambient lighting, and adjustable seat configurations, to reduce the likelihood of motion sickness. While some individuals may be more susceptible to car sickness in EVs, it’s essential to note that this issue is not unique to electric cars and can occur in traditional vehicles as well. By understanding the causes and implementing coping strategies, EV owners and passengers can minimize the risk of car sickness and enjoy a comfortable ride.
