The biggest drawback to electric cars is finding a place to stop and recharge if you plan on going very far. Then again, oil-powered vehicles force you to pull over and pay big bucks at the pump every 400 miles or so. Now, just imagine a world where you never have to look at how much gas or battery juice you have left because your car is charging as it goes.
It might sound like a fantasy world but roads that charge your car as you drive are a real-life plan in the UK. Highways England is in the midst of adding freeways that actively charge electric vehicles.
