Here's a thought! (My brainstorm?!?!?)...
The more EVs there will be over time, everyone's electric rates will go up. It will have to at some point.
Why? The proper time to charge an EV is at night when generating capacity is surplus. So much so utilities offer discounts for using electricity at night.
I was joking about the 1950s electric bumper cars. But they worked, no battery. The floor was metal as well as ceiling, so a contact between them ran the motor. I remember the ozone smell to this day.
Trolleys and pantograph trains work by overhead wires, they're on rails so even contact.
But...there is inductive charging. There's a unit for your phone. No connection, place phone on it and it charges by induction.
So why not wire coils underneath asphalt on major highways? An EV would get charged by driving along. Talk about a long range...even for tractor trailers or towing a trailer.
Induction charging of a moving vehicle is very difficult because you have one coil moving over another coil. Ever see that before? Doesn't it sound like an electric motor? It is. Requires more force to move one coil over the other than you can couple between in energy. Plus it is a highly lossy transmission medium. Doesn't much matter for a couple watts on your phone but for 20kW to move an EV at 70 MPH it gets significant.
