I like the avoid left turns onto major traffic routes idea as waze does NOT in fact learn to avoid such. Whenever I leave my apt waze always gives me a route that includes a left turn onto a major route. I occasionally play along and sit and sit waiting for a gap to make the turn in order to teach it that such a route is not adviseable during rush hour, but it has never given me an alternate route.
It doesn't even learn that going one block further west before attempting the turn will almost always get me turned faster due to a light managing the flow of traffic. No light needs to be plotted as traffic turning left there gets through every cycle (maybe two at most on really busy days), as to sitting for two, three or even four cycles of that same light while waiting to turn at the intersection Waze suggests.

I agree with this assessment. Waze had never learned my preferred route home after almost a year. It will more times than not still send me an alternate way.
I have to say that restricting left turns on heavily traveled roads until you get to a controlled intersection seems like a good idea!
I wouldn't want to be the waze guinea pig stuck and nervously waiting for a chance to scoot across without causing an accident when you could've been safely led several blocks down the road by going to a traffic light.
Just one of those things I've tried but not worth the aggravation! Or an accident possibly resulting in this type off dangerous move.
No automatic system can be as smart as the community. It's the local editor's job to identify problematic "left turns" and make sure there is a separate segment for that turn - if it's that bad, there should be a left turn separate lane for sure. Having a separate segment for the left turn and straigth ahead, waze will learn the left turn segment is slow and will then route people straight ahead.
I'd rather have the editors deciding if a left turn is safe and quick or dangerous by splitting the traffic information with relevant segments and then have the one algorithm taking care of it.
