Rental cars are still a thing. Plus they get regularly cleaned and you aren't responsible for their maintenance/depreciation.
If you live in a city -- and if you are getting municipal water/sewer, you definitely do -- there's a car rental place close enough that will doubtless be happy to do a same-day rental.
The car rental may be expensive, but you're comparing it to owning and maintaining that car year-round for those occasional trips. And if that car is anything bigger than a small suv, it doubtless costs more than the EV would've in real terms.
