I'm a little skeptical of the "half of the driving population won't be able to charge" claim. For example, you don't necessarily need to own your off-street parking spot for the owner to upgrade it to increase its value. And I doubt on-street overnight parkers constitute anywhere close to half of the population (I'd be interested in data that shows otherwise).
Anyway, it will be many, many years before even half the driving population switches to electric. That's a lot of time to figure out charging infrastructure in cities for the rest of us.
