For people owning an electric car as a second or third vehicle there is no difference in annual mileage compared to combustion engine car owners, while individuals that only own an electric vehicle report lower annual mileage; a pattern also expected for future car use. One can only speculate on why this may be. It could be that only people that really substitute a traditional with an electric car reduce their driving and thus have a positive spillover and there are features of electric vehicles limiting this (e.g., range limits). People who become car owners by buying an electric vehicle, on the other hand may increase their personal mileage, although not by the same extent as conventional car users4. People that buy an electric car as an additional car show no positive spillover effect on their travel behavior.
