Range anxiety, the fear of being stuck somewhere without a charge, continues to prevent some consumers from buying an electric vehicle, even in states like California which have more charge stations than other parts of the country. “A recent survey of 181 San Francisco Bay Area public charging stations, partially funded by the nonprofit Cool the Earth, suggests that 23% of them might be nonfunctioning at any given time, stymied by broken screens, shoddy credit card or payment systems, network connection failures, or damaged plugs,” per Wired.
