I only use public fast charging when on a long road trip. So the 30 min charge always coïncides with me emptying my bladder, so it's never been a hassle.

As I wrote, this was a rental, there was no charger where I was and no mains adapter provided with the car, so my options were fast charger or pushing the thing.

And even during long legs I don’t need to piss for 30mn every two hours.
