Some passengers in the UK and elsewhere say they feel more car sick in electric vehicles than in petrol or diesel cars, BBC reporting shows, though many EV owners say they have no such problem. Researchers point to possible causes including the missing engine sounds and vibrations that passengers normally associate with movement, sharp slowing from regenerative braking (where the motor recovers energy as the driver lifts off the accelerator) and quicker acceleration, but they stress that evidence is still sparse and largely anecdotal. It matters because EVs are fast becoming mainstream, with zero-emission cars making up 5.8% of licensed cars in the UK by June 2026 and new petrol and diesel sales due to be banned from 2030; experts advise affected passengers to look out the front window, sit in the front seat and open a window.
