Hopefully this is implemented soon. In the last couple days I've found at least a half dozen URs for this type of routing. It seems to be getting more and more frequent.

Waze staff has stated that they are addressing the circumstance when historic data creates unreasonable routes to cut time. It is acknowledged that many times, Waze prefers to continue straight, make a u-turn and turn right instead of just turning left in the junction just to save a few seconds. Very often this is perceived as a mistake and not as a time saving.

Waze is testing changes to the routing that will prevent such detours if there is under a 30 sec difference between the routes.

Here is another odd avoidance of a left turn. I can't reproduce it so maybe it was based on unusually slow times to turn left.

Just so that it is noted: If I would post every instance of this issue cropping up literally everywhere here, I'd spent hours.

Just *ONE* more example out of dozens (albeit showing two totally seperate URs at the same spot)

Here is a slightly different kind of apparent "routing problem" that would take the user an extra 95.3 miles and 46 minutes (those figures are from livemap routing laramie,wy to lovell, wy vs laramie to casper to lovell. The two step route is much shorter and faster. I admit that I have not checked every segment and node along the 404.66 mile route to make sure that there are no bad settings.)

Here is right/U/right with the unannounced U at a dead end. Raised here.

Another one, this time waze took a left and a detour to come back and avoid a (perfectly allowed) right turn.

It would be a *really* nice move if there'd be some official staement from Waze staff here.

It amazes me that WAZE is still having these kinds of routing problems, 9 months after this topic was started!

It seriously undermines the trust drivers put in the app.

Someone needs to take a long and serious look at the routing programs and fix this bug.
