Most people at sometime will have seen a metal channel with a 1/2 or so
slot laid across a pavement to take rainwater from a downpipe to a
roadside gutter.Many date back to Edwardian times but are still in place.
It may be that where EVs have to be charged in residential streets a
similar channel could be laid from premises to curb, problem would be that
the fast charging cables tend to be a lot thicker than 1/2 so to get a
cable small enough would need a rethink on chargers and voltages.

Heres a side street in Cambridge as can be seen theres hardly any room
to put anything anywhere. I reckon this photo was taken on a weekday and
during the day sometimes you simply cannot get parked anywhere near your
home so how ya gonna charge?..

Go along that road and you will see another version of the rainwater
channel I mentioned except it is the covered type rather than the slotted
by every downpipe.

So put the outlets on the house walls alongside the phone junction boxes
replace the metal channels with the slotted type that a cable can be laid
in and job done.
In practice nothing will be so straightforward and the lack of a dedicated
parking spot will be a problem.
Yes it isn't that simple is it?.
If its on your property and you can't park there;(..
Any cables from the wall someone will trip over them, only possible way
is to have a sort of overhead coupling device a bit like some very old
petrol pumps that had hanging hoses?
Perhaps we need an Overhead line system, bit like the railways up
pantograph
Running a tad less than the usual 25 kV..
One way would be what some areas already have is a residents parking
schemes and as EV use develops and an acknowledgment that the concept of
your own personal charging point is just not practical ,and though an
outlet may be on your front facing wall all such points are common use and
agreeing to that is part of getting
a residents permit.
Working out how costs are apportioned to the right account Ill leave for
someone else to work out but possibly
with outlets connected to the web and a terminal pad like found on railway
ticket barriers that people place a card /smartphone on.
Some may not like the idea of their infrastructure being used by others
but many others no longer have such worries and accept that people using a
WiFi point on their premises is just part of normal life.
Still it is all conjecture at the moment and until EV use becomes the rule
rather than the exception who knows how things will turn out. It may be
that for some car ownership will just become too awkward.
