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.
To a large extent an ole is an ole, ok it may need to be bit larger for a
power cable of the size required
but when the area I was then living in got cabled for TV by NYNEX the most
memorable part of the disruption they caused was the bloody mess their
marker paints caused before hand, we thought there had been a major
graffiti attack till we twigged what the various pink etc blobs were for.
That was for what was basically an entertainment provider who felt the
investment would be worth while even though many properties to which they
ran the ducts did not take up the system.
Those ducts ISTR were about 25-30mm diameter so a power cable would not be
vastly different if it was direct burial though I accept it may need a more
prepared surround.
One sod who did not take up the system prised the cap off the duct that
terminated inside his fence
and disposed of his motor oil down it which was a bit mean.
If digging up the streets was done fairly effortlessly so that Punters can
watch re runs of “I Love Lucy” and the cultural delights of East Enders
shouting at each other then doing it again for arguably less frivolous
purposes should not be the obstacle you make it out to be.
Meanwhile the utility industry is quietly getting on with replacing old
Iron gas pipes with plastic as leaks as well as being hazardous also
contribute to green house gases even if unburnt.
There is a lot of experience out there in digging the ground.
