Sure, but at night the car will probably be in place for, say, 10 hours, every night. Not faffing jumping between places and trying to find a public charging point. Even just driving to work and charging there is say 6 hours of continuous charging. The main block of time will still be at night.

6 hours charging is more than enough for work/school/shopping. On the rare occasion that you want to drive all day, you can add a night charge to that (before or after the drive as appropriate). Overall, the large majority of charging will (or can) be during the day.

I'm answering the question "why are most charged at night?" There's no point reading what I'm saying in isolation!

Also: people who live in apartments will generally find it easier to find a place to charge at work.
