My flat is about ~50m from the road and 3 floors up. I absolutely get what you're saying, but charging from a cable inside the building isn't practical for anyone in this block (or many of the blocks nearby).
Could agree more with regards to the explosive liquids - but you can be in and out of a petrol station in ~5 minutes. I may only need to charge once a week, but it still requires my car to be somewhere with a charging point for an hour (or whatever) a week.
FWIW, I don't have an answer. I just don't think we're there (or close) yet. I suspect EV adoption will start outsides the cities and spread in.
A government will instantly approve of a plan to install dozens of parking meters per block at a cost of thousands and thousands, and then employ an entire department to wander the city and enforce the rules. It really can't be that much harder to make it so that some of those meters also work as a charging station.
I imagine as battery and charging tech progresses, the difference between getting petrol and charging a car will narrow to the point that it really doesn't matter. e.g. For the better part of a decade Tesla had been able to charge to 80% in ~30 min. That's more than enough for the average city dweller to get their shopping done. This is one area where I think techno-optimism is extremely warranted.
I'd assume eventually it will work exactly like you suggest - I just think we're very far from it right now. I see it very much chicken and egg - trying to encourage your local council to put charging points every 3 or 4 spaces on every street is going to be next to impossible when there's just not enough EVs; too much hassle/uncertainty to own an EV in the middle of a city if you have to park it on the street (and your charge options are super limited).
That said, I'm sure it'll change and change will come quicker as more people in the suburbs (with the space to charge at home) buy.
If you have a car in the city, you probably only need to charge once a week depending on usage, is it really that outlandish to think that in an entire week you won’t take your car somewhere with a charger nearby? Besides that, you can slow charge off mains voltage using an extension cord in many cars.
We have wired every room in every building in every city across most of the globe to have electricity. I really don’t think it’s much of a stretch to run some extra wires to the curb as ecar adoption rises. The current system of moving billions of gallons of highly explosive liquids to custom built dispensing facilities placed every few kms on valuable real estate is far less practical when you think about it.
