Wrong, wrong, and wrong. I rented EVs multiple times. You don't worry about charging as often as 12 out of 48 hours. If there happens to be a convenient L2 charger you plug in. Otherwise you visit a fast charger.

Superchargers have excellent availability and uptime.

EVs depreciate quickly entirely because of technology advances. In the span of a few years we have seen 800V architectures, LFP batteries becoming commonplace. And semi-solid-state batteries are on the horizon.
