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?

They won't all need to fully recharge a car every night.

Of the many cars parked on a street, plenty of them just aren't used
most days. And of those that are used on any given day, plenty aren't
used much - just a trip to the shops, or the school run, or to a nearby
employer.

This depends a lot on the local demographic. There are plenty of estates
where at least one breadwinner per household is likely to drive to work
(and the national average commute is 67% by car, 30mins).

Where I live that's dominated by the 35 mile round trip to Cambridge,
unless they take the fastest route which is 50 miles round trip.
