The Uk is making decent progress on this already. I live in a London suburb and there’s been a huge rollout of charging points already - within a few hundred meters of my flat there are at least 6 high voltage charging points. There’s also a big rollout of charging points built into existing lampposts - by tapping existing power lines these are very cheap to install. The chargers are run by a few different networks but you pay for usage so it’s quite possible to just sign up to them all and carry 2 or 3 cables.
