“Davis, at Berkeley, found that in multi-vehicle households, an EV tends to be the secondary or tertiary car. Some two thirds of households with an EV also had a gas-powered car that was driven more often. What’s more, that vehicle is more often than not a relatively inefficient one — namely a large truck or SUV…’That’s bad,’ Davis says. ‘If EVs are going to be an environmental solution, it hinges on them being widely adopted beyond what’s a niche product for rich people.'”
