Yeah, but that is only in London and only 1300 street lights. Once they've done 10+ million of those in the whole of the UK this might get interesting. And it will still be much more expensive to habe an EV for people who cannot charge at home.
Sadly they haven't even started with that here in Germany. And tbh, I am quite annoyed by this. They keep blowing money into the assess of suburbanites, but completly ignore urban people. Thus subsidizing infrastructure wasting sprawling even more.
