There's a decently high current power line available from street lights. Not sure if they're still putting them in with high current since so many are converting to LED, but sodium lights drew ~1kW iirc.

There's already been projects to put in chargers on street lights, like this one https://lalights.lacity.org/connected-infrastructure/ev_stat... and this one https://www.electronicspecifier.com/products/renewables/conv...
