Hmmmmmmm...
I think you’re on to something.
The car of the future operates as 100% EV for local driving.
For state and Federal highways, an armature extends beneath
the car and connects to a metal ‘slot’ which conveys
electricity to the vehicle. The entity managing the road
charges a toll by the mile for the electricity and you arrive
at your destination with a fully charged vehicle.
Easy Peasy...
Yeah, I get where you were going. But I was talking about RC cars. However, I love this video (great Brazilian band). Surprisingly well done.
