What I’m expecting:
A solid state battery that gives 1000 mile range and recharges in 15 minutes.
What I’ll probably get:
Look at the new paint colors now available!...........

A hybrid that charges as you drive would be a good idea too.
It’s hard to imagine a real-life perpetual motion machine, if that’s what you’re talking about. But hybrids and BEV’s do have regen braking to charge the battery up some with the braking we do every now and then anyway with our normal driving. So far at 80K miles I haven’t needed brake pads replaced, supposedly because our EV’s braking is mainly from regen (though we use a little brake pad braking when we slow down faster than regen brakes).
