Big fan of this. Obvious plus for pedestrians, and it should actually clean up the confusing Woodward/Jefferson intersection for vehicles. All around win.

As far as people unfamiliar getting turned around... those people are already following their GPS for navigation anyway, so they will be fine. It will probably be the person who is familiar and forgets who gets caught off guard. But in either case, you just go one block over, turn around, and your fine.... no big deal.
