I've got some streets laid out, with the curbs cleared of any trash and rocks that might damage a speeding rover.

There's RTG powered lights strung up along the side of the road, and a tiny O2 tent by the intersection powered by the same RTG that runs the nearby streetlights.

Farm up north, and original base with hospital down south-east (you can see the parking lot at the edge of the map), and a buggy repair shop halfway up the north road.

My low oxygen isn't a problem since I can cruise at full speed up the highway without needing to refer to the map, and the farmhouse lights tell me when to turn in to the driveway. The automatic airlock helps too :)
