Yeah if you've got home charging it's not a real issue. We use 240v here in Aus so you can pull quite a bit out of domestic outlets before having to get serious and generally overnight charging to top up the day's commute would be fine.

So it wouldn't be a fast charger on every street, and you could always enforce limits by time of use pricing to put a dampener on peak loads.

I just wonder if utility planners might get caught with their pants down on this one. Like, could you say 5 years ago chargers might run to 800kW?
