How can you describe such a gargantuan infrastructure project as "easy"? You're talking about power structures and associated transmission to virtually every carpark in a city, as well as a way to monetize it.
It’s like that here in the NL. My power company has an EV sparking spot on every block in my neighborhood. I rented an EV for a weekend and was pleasantly shocked at how easy it was to find a charger. Well, as long as you’re not in Amsterdam. Amsterdam is hell in any kind of vehicle.
I say it's easy to make L2 street parking ubiquitous _anywhere_, not _everywhere_ all at once.
Obviously taken in totality it's a massive undertaking, but you could say the same thing about streetlamps, or roads, or basically any ubiquitous infrastructure.
Many places have started with 1-2 spots per neighborhood, which is prudent and scalable. As demand rises they should be able to keep pace with that demand without significant technical challenges.
That’s potentially plenty though. You only need street charging for a relatively small
Percent of the population. For most drivers 1 night in 3 would keep you fully charged.
