Electric Roads Could Be a Path to a Driverless Future

BEIT YANNAI, Israel — Electric vehicles can significantly reduce greenhouse gas emissions, at least in theory. But challenges to wide acceptance remain significant: Batteries are expensive, charging stations are few and far between, and recharging takes far more time than a fill-up at the pump.

A technological breakthrough is needed, and many companies are working on ways to make charging faster and travel range longer. Advances have been frustratingly slow.
