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.
Even assuming you can distribute enough power to make them function,
there aren't enough lamposts available for all the people who are likely
to want to use them.
So add some extra charging posts, like parking meters of old. There are
also charging points which recess flush into the pavement when not in use,
already available.
The alternative is to provide charging at the other places the car spends
most of its time. I've not had access to my charging socket at home for
around six months, and have survived quite happily charging at work or at
the supermarket. (Nb I'm not in any way claiming that'll work for everyone,
but I bet it would work for a lot of people)
