Observing the Chariot Routes, it was noted that the south-bound chariot from Valley of the Kings does not stop at Desert of the Shades, but goes straight past to Fool's Paradise.
This means that anyone from Red Sea Oasis and Desert of Shades must take a tortuous route to get to Valley of the Kings, Pharoah's Bay and Nile Delta; and vice versa.
I propose that the south-bound chariot from Valley of the Kings will change to stopping at Desert of Shades, from which there are Chariots on to Fool's Paradise and Red Sea Oasis.
