*Can you really not see that applies regardless of where domestic

And where did I say it didn't[1]?* But that's a different issue -
orthogonal to your claims* about the ease with which charging points
could be provided and the rarity of ADMDs of 2kw or less.

[1] assuming of course the usual but not universal sharing of local
distribution cables by street lights and homes.

Street lights in residential areas (rather then trunk roads) are
[only] around 50watts each, and tend to be wired up on local
daisy-chain cables a bit like household ring mains. They are down in
the noise level compared to EV chargers (or even the infamous 2kW per
household).


My reference to street lights sharing distribution cables with homes
was because some people seem to think that it makes a huge difference
if charging points are on drives or on the street - the latter in
residential areas often meaning on street lights.


The fallacy is that because there's a street light (consuming 50 watts)
it should be possible to install a 7.4kW car charger to every one.

Or in fact several to each one, because on-street parking bays are
typically 8-10 per streetlight.
