That’s a not inconsiderable advantage!
It is, but otoh once - one hopes - street recharging via some sort of
infrastructure built into street lights or similar for those who
don't have
driveways becomes the norm in a decade or 2, that advantage will become
redundant except for the very few people who need to do ultra long
journeys
without much in the way of stopping.
The main issue with EVs isn't the battery vs H2 argument , its where
the power
is going to come from to power them all in the first place because
right now
the generating capacity simply isn't there
And nor of course is there much more than 13A ring main linking up the
streetlights in any one street.
Streets and pavements are dug up often enough for other reasons, that doing
it again to upgrade the wiring/install a parallel circuit, isn't the end of
the world.
I think you underestimate the scale of the project.
The various cable TV/internet companies, now all(?) under the Virgin
umbrella, laid new cable along the pavement of a decent proportion of the
country in the 1990s(?).
Just under the surface (and in many cases very poorly finished), power
cables have to be much deeper - 18" is typical.
This time, for a start, only roads which people actually park along will
need to be covered. That rules out a good proportion of residential roads
which are sufficiently provided with off-street parking.
You'd probably have to do all the ones which currently attract cars
parked on them. Which in a lot of places is pretty much all of them.
The often wandering path of the cable track for cable television
(still visible years later round here) gives away the degree of
shoehorning into place that was needed in many places to fit it
alongside existing services. Any work on electric cables is observed
to involve digging past cable television, telephone, gas, water,
drains, etc. which themselves aren't always neatly arranged.
