for the charging hot spot in my driveway apron, i have installed 4 separate locations in the corners of the apron and driveway.
for three of the outlets i use a 12AWG romex loop. the loop is tied back together under the front porch to the service panel which will have a 60A breaker. so i can charge up to 60A at any of the locations, or have three, up to 6, separate vehicles charging at 20A/240V.
the fourth location has 10AWG romex also buried under the concrete, and from that spot i can take up to 40A/240V. 2 vehicles can share that outlet.
so i could charge up to 100A/240V in my driveway anytime. i expect that eventually the charging will be divided between 6-8 vehicles parked in the driveway or on the street adjacent my apron where people in the neighborhood can leave their car parked overnight and allow everyone to charge at a more modest rate to conserve the total capacity of the power i can deliver to them.
so assuming a 14 hour charging cycle overnight, 336,000 Wh for each night and if they each get 140Wh/mile that is enuff each day for 2,400 miles total over all the vehicles. each day.
so distributed neighborhood charging spots can serve a huge base if they are ubiquitous. the problem is the city code restrictions on allowing people to implement solutions of their own which do not require installations by unionized electricians with all of the excess expensive equipment that the city requires in their code rules based on the (corrupt) financial interests of the EVSE sellers.
my charging spot is actually totally illegal and 1/2 is installed in the parking strip space that the city controls so it is totally illegal. which is the case for almost anything i need to do to improve my house and charging spot.
