On the fastest lane of the moving road between Niv Luáivai and Iangboro, a passenger is murdered. How can they track down the killer? This is a huge ring of a road; the culprit could still be on the road, or hundreds of kilometers behind (having transferred to a slower lane, disembarked completely, or transferred to the counterclockwise lanes).
Oh, and given a density similar to that of Earth and gravity 0f .7744, how much smaller is the curvature of the world, and by extension what is the widest the Heinlein road could be?
