What's important for the EV-charging scenario is that is if several
dozen houses are supplied by an 200A street main at 230v from the local
substation, how can more than a handful charge an EV overnight at 50 amps?

The grid will eventually have to be upgraded, though for domestic use,
an off peak slow charge at 3 kilowatts is usually enough for a day's
use. The street main is usually 200A per phase, though.
