People still complain that it's not possible to charge EVs at their parking garages in their condos in such a developed countries like Japan. We even have these things.

The problem was already solved and available.
These types of automatic mechanical parkings are already available from multiple major parking vendors, and they are common (at this time, still without charging) in Tokyo condos. Newer condos will have these with charging by default because EV charging is cheap and future proof.
It just takes more time to get understood and adopted IMHO. Not one single reason is the sole blocking issue for higher EV or Tesla adoption.
When I installed HPWC 80 amps in central Tokyo (for my office) I had five parking garages available to rent. One was mechanical and big enough but didn't have charging trays. For other four buildings owners gave me estimates for installing 200V 80A circuit and an HPWC. They ranged from $7k to $40k. All of those buildings were receiving 6.6kV feed from the electric company and had their own transformers.
I went with $7k one, which didn't include upgrading transformers, and paid for the cost, happy. The other parkings required upgrading transformers. Here, those last one leg transformers are building's properties.
My condo doesn't have EV charging and we have about 20kW extra capacity available with the transformer. One HPWC or CS-100 possible, but only one car space available. We need to let people use the charging space in turn, in about 70+ house condo. FYI 70+ housees, only 16 families own cars.
This is in Tokyo. I've been to China a few times and yes China is much bigger - in terms of space but infrastructure?
The North America has lots of space, that's one of the main difference. With space you can get one more feed from electronic company, upgrade one, install chargers, etc. With condos and small houses it's going to be difficult.
Some people (even in Japan!) have mis-information that they will get higher electricity costs with EV. Or people don't know about Tesla. At all. I wish to post "Tesla moments" thread some time in the future but during my 5 month ownership and 11k kilometers driving I had only one Tesla time, because nobody knows about this car.
