Observation and question from a noob....
[Assuming for this discussion that Bluebonnet/Coursey run north and south and that Airline runs east and west]
With the restriction on the U turn in place, it doesn't seem that Waze knows that you can proceed north on Bluebonnet and through the intersection to turn left onto Airline. If you are proceeding north on Bluebonnet, the only turn that is permitted at the intersection is a right onto Airline. There is no way to proceed up to the intersection with Airline. Therefore, Waze will take you east on Airline until it finds a junction to make a U turn so that you can proceed west on Airline to take you back to your destination.
So, why not simply change the arrow that restricts the U turn to green and allow drivers to proceed north on Bluebonnet? Or change the intersection to a bowtie and restrict the U turn going south on Coursey at the appropriate juncture?
I think this intersection is a work of art. I wonder if something like this would work better for the Bluebonnet/Airline intersection. https://www.waze.com/editor/?lon=-118.5 ... TTTFTTTTFT
