Nah - renters didn't want them. Nobody wants a care for 48 hours on rent out of which at least 12 hours it has to worry about charging it.

Superchargers aren't always available or in working condition even if are nearby.

And EVs don't deprecate faster because technology is advancing by leap and bounds. It has other factors.

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.
