More like a couple times a year for me. It sound viable, but it really isn't because the cost is so high - it is cheaper to have a (used) car that works for everything than to spending $800 to rent a car for a week. I visit family out of range of an electric car for many holidays - cheaper to buy a car just for those trips and park it than rent a car for those trips!

I'm not against renting a car, but it is far too expensive in practice to do for a regular vacation.

If you take 2 trips a year, each time staying a week, that's going to cost you $1,500 a year.

For that much money you could just buy another car.
