An analysis of variance indicates that participants who purchased an electric car have on average a significantly larger number of vehicles per household than those who purchased a normal car. Nearly 50% of normal car buyers only have one car per household, 44.5% own two, with only 6.1% own more than two. For electric car buyers, only 9.5% have it as their only car, whereas 75.7% own two cars per household and 14.9% own more than two. This means that electric cars are generally bought as an additional vehicle and not as a substitute for a conventional car; a result that differs from De Haan et al. (2006) in Switzerland
