It's a capital expense to make the upgrade, and a political question of what should be done to require/encourage it.
All you really need is a standard 120V outdoor outlet at each spot. Consider that for every one or two cars that need a single outlet (even if you put it on a dedicated circut), there is an entire apartment with about a dozen circuts, multiple outlets per circut, likely a mixture of 120 and 240 outlets, and several appliances that switch between 0 and 100% load unpredictably.
If we can figure out the electrical engineering to make that work, I don't see the problem with wiring a garage for charging.

1) While that does technically work, it will be pretty slow. My Tesla Model Y charges 3-5 miles of range per hours on a 120V outlet. Perhaps fast enough for most though.
2) I was just in the Canadian Rockies (with said Tesla) and all outdoor parking spaces had outlets. AFAIK they were for the block heaters for harsh winters. It made charged over night slow but nice. Any parking space had them. Cold climates accidentally made it super convenient to park and charge for long stops.
Installing a 240V or 208V outlet should be just as simple, although the result will be less convenient for anything someone might want to do with a power outlet in a parking lot.
Although, if you are wiring a 240/208 circut, you should be able to use the same wiring to drive a 120V receptical.
My prediction is that there'll be a growing business of vulchers putting in pay-per-use chargers in large apartment buildings that the landlord gets a kickback on, much like overpriced washer/dryers.
