So, here in Spain, electric cars can't be the solution for the vehicles and having hydrogen cars would certainly be the way to go, it seems.
We can use already built infrastructure and we don't need a charger on every single street.
In Spain, 70% of the vehicles stays on the street overnight[1], that means a charger every roughly 10 meters. Imagine the amount of copper necessary to cover that.

Imagine how much copper would be needed to supply electricity to every house!
If Spain happens to already have a system that supplies electricity to every house in place, then the amount of copper needed to string some up to the road would cost less that the price delta between petrol and electricity in most places after a single month of electric vehicle use. I know because I've strung copper from my home to my parking space, three phase, and I did it for financial reasons.
I love the reasons that people invent to try to oppose electric vehicles. Think of the copper!
I'm not opposing electric vehicles, I'm just trying to show a different reality here.
In Spain you need a permit for almost anything and one of the reasons we don't have more chargers is just because of bureaucracy.
Right now, if I had a car and it was electric, the only option I would have to charge it is running an extension cord from my balcony to the car (Supposing I parked right in front of my apartment).
This is a real challenge and I wish the government would focus on the infra needed to: Assemble batteries in the country, create more and more charging points (As I said before, 3 streets had a cost of 200k€, and they are not even covered completely) and remove taxes from electric vehicles. I think that's what works but here they chose to make life difficult for everyone with a gasoline-powered vehicle.
At least the government is investing in public transport

Not every single one of these cars needs to be charged all the time - and in any case, most people drive short enough distances that they can be charged at a simple 230V outlet over night, which means it would be enough to add outlets to existing street lights. Alternatively, employers, shopping malls etc. can provide charging opportunities in the exact same way. The only place where high-power chargers are needed is for people commuting long distances.
In any case, the goal should be to take as much individual car traffic off the streets as possible by providing usable and affordable mass transit as well as usable bike infrastructure.
Even crazier, there was a time where someone proposed running at least one copper pair to every home just so people could talk to each other over long distances. Two wires per home! That's impossible.
On one side of my street there are 4 streetlights and 16 cars parked almost at all times (At least from September to July, the only time you can find a parking space is early morning).
Would that be enough? The streetlights are LED so I don't think they use too much electricity to justify a massive cable that could charge 16 cars
Likely when built the streetlights weren't LED, so the buried cables are under-capacity. Assuming they can provide 230v power at 15-20 amps, that's enough to fully charge something like a Tesla or Chevy bolt (250-300 mile range) overnight.
Most people could do fine with charging only 1 out of every 4 nights for regular commuting, the tricky part is just figuring out how to make that work logistically, but it is at least feasible. Those with schedules that allow charging during the day make things easier I'd assume.
Of course they're under capacity, but it's not that expensive to replace and upgrade the cables to be able to support a couple standard car charger sockets - just do it when someone else rips up the road anyway.

The what now ? There are way more cars than street lights and most people do not park in range of one (with reasonably long cable).
And I am absolutely sure unplugging people's car would become favourite teenager past-time anyway...
I agree that the goal needs to take car traffic off the streets, that would be the dream. I don't own a car and I don't plan to do so because on my city I can pretty much do anything I need to without it.
I wish it was as straightforward as adding 2 outlets on each street light pole but the government will still need to charge people for using it and well, if each pole could charge 4 vehicles at the same time, it could even work on my street.
Just wait a few years when photovoltaic roofs will become the standard. Cars seem to get driven 10000km/year on average in Spain, which is around 27km/day which is doable with solar car roofs. I guess especially for people living in cities it should be less.
