I think for me the question is. If you are charging your car on a streetside
charging point, what sort of cable is uses and is there any circumstance
where it can become a trip hazard to a blind person. I remember when
electric cars first came out the idea was mooted of a kind of swing arm at a
high level with the cable on it to drop down past the curb to charge the
car. To me that looks like a vandals paradise, and to leave a cable trailing
is a h/s nightmare for being sued.

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?..

Does each house currently (NPI) have its own petrol dispense point?
No of course not.
You will take your car to the nearest garage to fill it up.
Battery and charger technology are already available to chatge to 80% at
350kW.
For an average 200/250 mile EV with a 40kWh battery that will charge to
80% in about 7 minutes, just a tad longer than the normal petrol tankup
time.
Plus you will be able to top up at virtually any public parking place
eventually - supermarkets, public car parks etc etc.
Yes the infrastructure is not quite there yet, but give it another 7 -
10 years and we will be there.
Battery and charger technology development has never had so much money
and manpower thrown at it in the history of the universe.
Battery capacities and charge power will steadily evolve.
