If you regularly drive some of the busiest highways in the US, you now have a stronger incentive to pick up an electric car. BMW, Volkswagen and ChargePoint have finished installing 95 promised EV charging stations along key routes on the US' eastern and western coastlines. The chargers, typically placed about 50 miles apart, will help you travel from Boston to Washington, DC (mostly along Interstate 95) or Portland, Oregon to San Diego (on Highway 101 and Interstate 5) without worrying about your battery.
