You're missing the point. Who is going to pay to extend electricity into each car bay of an apartment building car park ? It's a significant cost that any property developer is not currently doing (they clearly see a weak market) nor likely to do for the handful of people who will request it.

Much of a future hydrogen distribution network already exists (we have transportation companies, gas stations etc) all of whom would be more than happy to add a new technology. Just like they have done already with LPG.

Most apartment buildings didn't have A/C when they were built either. The building I'm in is nearly 120 years old. At some point the landlord ran extra cabling and dedicated outlets so we could have window air conditioning. I imagine that was as expensive or more than car charging stations would be.

The market demanded it, landlords provided it. Keep in mind landlords are in the business of finding ways to deploy capital to increase their rental incomes. That's why they upgrade kitchens and floors - because they can raise rent. Much like air conditioning once was, having an electric car charger certainly seems like an amenity you can charge for.

It's not massively cheaper to solve the problem of the building itself requiring some multiple of its current electrical service supply once all the tenants want to start charging their cars there.
