As electric vehicles (EVs) become increasingly common, a new concern is emerging among drivers and passengers: motion sickness. While EVs offer numerous environmental benefits, their unique driving dynamics are causing discomfort for many users.
One of the primary culprits is “regenerative braking”, a feature that allows EVs to slow down by converting kinetic energy back into the battery. This system, while efficient, can be jarring. “Strong regenerative braking can cause motion sickness,” confirmed John Voelcker, former editor of Green Car Reports, in an interview with ABC News. He noted that the abruptness of this braking style requires drivers to modulate their use of the throttle carefully.
Ed Kim, president and chief analyst of AutoPacific, echoed these sentiments, stating that Teslas, in particular, are “very jerky and really abrupt.” Kim highlighted that the high torque and rapid acceleration typical of EVs contribute to the discomfort, as they differ significantly from the smoother acceleration of traditional internal combustion engine (ICE) vehicles.
Dr. D.J. Verret, an ear, nose, and throat doctor, explains that the lack of sound in EVs can exacerbate motion sickness. “The brain sets up a model for what it expects in certain situations,” he said. In an EV, the absence of engine noise disrupts this process, leading to a disorienting experience for passengers.
These issues are not isolated to anecdotal reports. Monica Jones, an associate research scientist at the University of Michigan, has conducted studies showing that passengers are “very sensitive to the jerk” caused by regenerative braking. Her research indicates that the abrupt start-stop motion significantly increases the onset of motion sickness.
Manufacturers are beginning to address these concerns. For example, Hyundai’s Ioniq 5 N includes artificial engine noises and synthetic gearing to mimic the feel of a traditional gas-powered car. This design choice aims to reduce the sensory dissonance that contributes to motion sickness. Similarly, Cadillac’s Lyriq has been praised for its gentle acceleration and smooth ride, offering a more comfortable experience comparable to ICE vehicles.
In summary, while EVs represent a significant step forward in reducing carbon emissions, their unique driving characteristics are causing unexpected health issues. As the industry evolves, both manufacturers and drivers must adapt to ensure a more comfortable and enjoyable ride for all.
