In fact "installing chargers" isn't the main problem.

boltar stated "the majority of people in this country ... don't have a
driveway" which is what I was questioning.

Neither garages nor "other off street parking" equate to "driveways".
Houses (and increasing so in new developments) have garages in blocks
some distance away. Again, often due to planning fashion, trying to hide
them away from view. Or older properties with garages at the end of
their garden reached by a narrow lane down the backs of the houses.

I think we should agree to disagree on how difficult this will be. I
know people who have installed EV chargers in places that weren't next to
their home and it was complicated but achievable and they were the first
to do it.

Early adopters will pay vastly more than the economic payback for
fashion statements like that.

I think it will get easier, there will be local installers to
take away the hassle etc.

Digging 2ft deep trenches in the road (there's one near me this week for
a brown-field new house) is neither trivial nor cheap.

And as I've said, there's little point in connecting yourself to a local
distribution network that's simply not sized to accommodate EV chargers.

It's upgrading the local electricity supply infrastructure to be
able to cope with the extra load (even assuming central generating
has the capacity).

I don't really know about that. I've seen some people claim smart chargers
which know how busy the local grid is will save the day. If I had an
EV I'd plug it in almost every time I parked at home but it wouldn't need
anything like a full charge most of the time.

The National Grid has done extensive studies of this and has concluded
there are many homes which have little prospect of supporting EV
charging in the foreseeable future because the local supply is only
sized at about 2kW per property (and most of that will be used up by
existing consumption patterns).

They have predicted that overall generating and supply capacity would be
saturated at about 20% EV penetration, and that's if they spend the next
decade putting some remediation measures in place. And if every possible
smart/off-peak etc tuning is done.

I can't find that study, do you have a link to it? I found
https://www.nationalgrid.com/uk/arti...ams-future-evs
which is more than a little vague.
