Electric "floating" rental cars work very nicely. In many European cities there are fleets of rental EVs which you unlock with a smartphone. The cost is per-minute, or you can prepay a longer time, like a day.

I typically use them for moving bulky stuff around the city and small day trips outside the city.

There's a 20 minute free credit for ending the trip at a slow charger which is usually easy to do and means the cars are usually close to fully charged.

(I still wouldn't want a surprise EV from a normal rental company.)
