Why not just rent a [gas] car? Is it a long trip or are rentals there expensive? We’re traveling up to a rural area this week and there are no DC fast chargers. Rented a Camry for $35/day.

I agree somewhat. When I first got an EV in 2015 I think the off peak EV rate was about $0.10. It only grew a little bit for a few years but around 2020/2021 it jumped from $0.14 to $0.24. They blamed it mostly on rising natural gas prices. Still about 50% the price gas but it used to be about 25%.
