Using street lamps as EV chargers

ive always wondered why, in "day stay" car parks (commuters etc) they dont have 6 to 8 cables from a charging point that can all connect to different cars and then do round robin charging. This solves the problem of one person being connected all day and preventing others from benefitting. This way a number of cars can be charged up without the inconvenience of just one person being constantly connected. We have chargers at work where this solution would prevent all the car shuffling and aggro associated with people managing access. in our case 3 cars could charge in a day, so 3 cables available to three spaces and charging done round robin. Probably not a novel idea but one id like to see implemented

This is a very solved problem. EV chargers can change the rate at which the car is charging.

I have a double-charger at home. If I plug in one car, it gets 40 amps. When I plug in two, both cars get 20 amps until one finishes, then it does a 32/8 split with the charging car getting 32 amps and the idle car getting 8 amps.
