Electricity wouldn't be an option for exploring / driving extended off road trips for most. An enterprising owner could use some custom PV/mounts/wiring, a battery or cap buffer, and some power electronics provide off grid charging.
Someone could do this with any EV, but tossing it all in the back of a pickup is easier than a sedan or even an SUV.
Is it really that high? That’s what I pay in New York City.
