"don't have a garage where we can install such things"
Why? In the frozen north its, maybe not customary, but not overly unusual, to have parking spots wired for engine block and battery heaters. Theres a whole cultural thing of not blocking other peoples access, a legal framework of not blocking sidewalks, when its OK to share, or not share, someones extension cord, stuff like that. Its just not a serious issue. The cost of one parking spot was rolled into my bachelor pad, but when space was available I could get another spot for $25/mo or whatever it was, surely a charger spot would have some minor additional costs, but chargers are pretty cheap compared to land and pavement and buildings.
I guess the only technological limitation I can think of is service drop size, if you wire up 200 parking stalls at 25 KW each you're probably going to have to upgrade the service drop or implement something "interesting" involving partial charge rates. Presumably someone will start shipping an apartment charger that can bluetooth pair with its neighboring chargers and cooperate such that the total average draw of the entire lot never exceeds 100 KW or something like that. 100 KW is a drop in the bucket for an apartment building, thats like 1000 watts worth of TVs or lights in each of 100 apartments. Dinner time on a hot summer night is a large multiple of that draw.
House service drops used to be just 60 amps a few decades ago and now 200 is pretty standard... if you think service drop upgrades for a house are expensive, imagine the cost of an entire apartment building upgrade LOL. Of course this may be a short term thing... solar panels may mean apartments will be net producers while the sun is up, soon enough.
