>> presumably every lighting pole will have a charging point since they are on the last century grid.

The new light poles in my area all have solar panels. The solar+battery kit is cheaper than the cost to run the underground wires. The real jokes is that with the days so short, and the nights so cold, some poles are running out of power just before dawn. There have been experiments with running intersections (traffic lights etc) on solar as that can really reduce installation costs at remote locations.

Roundabouts. If it's that rural, why put in traffic lights?

[sandworm101]

Because is it rural. Farmers don't like having corners of their fields clipped to facilitate round intersections. And roundabouts have to be made large enough to facilitate multi-trailer trucks, not to mention farm equipment. Plowing them in the winter is also a real hassle/cost as opposed to strait-through square intersections.

Search "mini roundabout" [1], although these are mostly used in urban areas. In Britain, junctions in rural areas usually just have "Give Way" (i.e. yield) signs for the non-major road.
