One key point is that the shared one way loop concept is extremely flexible. Any entry point for any line will work. The streets I have shown (Wilmington, Lane, West, and Martin) seem like the best balance to me, but there are other possibilities too. This plan is counter clockwise, but to go clockwise use Blount on the eastern edge instead of Wilmington. On the north, Jones or Edenton would work too. Same for Harrington or Dawson on the west, and Davie and Hargett on the south. I think focusing on the concept rather than dogmatically insisting on a specific plan is probably the best way since it invites further investigation and study, and is harder to just reject outright on the basis of some specific nitpick.
