Not sure about OP but I live in the American southwest and that would be a pretty normal weekend trip. No 240V outlets in the desert, and if you run out of electricity and can't get ahold of someone you will likely die unless you can find a water source quickly. A 5 gallon jug of gas in the bed will generally at least get me to a spring if I run out of gas -- perhaps there's the 5 gallon jug equivalent of extra batteries?
I'd also note the depreciation on toyota off-road capable vehicles that would go on these kind of weekend trips (like gas rav4 / tacoma) is stupid low. Like stupid stupid low. To the point many people who bought new in 2020 might get more money now than before they drove it off the lot. Not sure if there's any EVs with only ~29.5% 5 year expected depreciation like say a Tacoma Toyota has.
Shifting the subsidy onto some other poor sod doesn't eliminate the depreciation. It's like saying I didn't lose money because grandma gave me $7500 to buy the car.
I don't own a car (I only do occasional weekend trips, so renting as required is much cheaper). But both of the two trips I've done this year met your criteria. They were camping trips to campsites without power outlets available.
