Which is weird, considering there's 3 phase AC 400V infrastructure everywhere in Europe. Putting 7-11kW slow chargers in every apartment's parking lot would be perfectly doable.
Do note that many apartment buildings in europe are 100+ years old and where not built with parking lots.
Commonly, cars are parked on the street outside, and therefore there is definitely not enough space outside an apartmentbuilding for cars if all apartment owners had one.
In modern, and newly built apartment buildings I imagine that this is probably already in place due to eco-hysteria.
If there's no parking lot, that's a car problem, not an EV problem. This is a hairy issue, but in my experience, getting around in densely packed city centers with a car is asking for trouble - dense traffic and generally no parking spaces.
I did use to live in a place like that, and I stored my car in a P+R on the outskitrts of the city.
Even owning an EV motorbike is sometimes difficult, I have been looking for an e-motorbike/moped and there are only a couple of models with an extractible battery and only one I have found that has the battery that is easily transportable (you pull it like a trolley bagage) when your bike is staying in the street: The Silence S01 and S02 (S01 being also sold under the Seat brand).
I bought my Taiwanese Econelo e-roller from Netto for 1.400 €. I can take out the 5kg battery and carry it upstairs to charge, but I also put down a charging cable from my kitchen to the parking lot. When driving around I have the charger with me, and I usually charge at work also for 2hrs. Because the range is only 40km now.
