Realisticallty - if it was a new norm - what additional cost would
it be for new builds to have a 3 phase supply brought to the meter
enclosure for possible use for a car charger?

Most comments seem to consider charging a single car.

A lot of families are two car these days, especially in suburbia and
outwards. We were 2 car when we were both working. Teenage kids at
home can easily lead to 3 or 4 car families.

At what point does it become infeasible to charge multiple cars
overnight using a single 80 or 100 Amp 2 phase supply?

Noting in passing that a decade or so back planning for new builds
restricted parking to 1.5 cars IIIRC so most new build parking is
likely to be in communal bays not on your own property.

You are saying that everyone you know uses up the maximum range of
their car every single day? Do you re-fuel your existing one every
single evening, then?

I thought TNP or someone had estimated current car usage from a
countrywide petrol supplied/annum figure. Doesn't this lead directly to
a total mileage/charge requirement if we all went electric?

That's not the same as saying every house has to have provision to charge
several cars at once.

Indeed. But it does point to the likely daily energy requirement for the
country and from that an idea what needs to change.
An example of restraint occurred here where a rural development of 4
dwellings was unable to use air source heating because there was
insufficient cable capacity in the lane.
Overnight load shifting will obviously help.
