Like much of Silicon Valley, there’s a regular flow of Tesla, BMW, Nissan and Google electric cars that cruise past from their nearby headquarters, and Cruz rather likes them. “I really wouldn’t mind having an electric car,” he says, though his first choice is probably a Honda or an Acura. Regardless, for now, he rides the bus. “I need to save up for a car,” he explains. As Cruz waits, a newly purchased Tesla zips by, advertising “ZERO EMISSIONS” on its license plate. Electric cars have never been closer to the mainstream, the market pushed ahead by California subsidies for electric car buyers, and a wide array of new models from established car firms such as Toyota and Chevy. Tesla’s focus on luxury, high-performance vehicles has also broadened their appeal; electric cars are no longer purely an environmental statement, but a tech status symbol too. Yet the “zero emissions” claim grates on some experts, who have continued to argue over whether electric cars are really more environmentally friendly than gas guzzlers, once the manufacturing process for the vehicles and their batteries are taken into account.
