Pretty sure from some limited sampling that waze is responsible for this cluster [1]. If you zoom in you can see the right-turn only sign at the intersection. What you cannot really see is that two blocks of cars waiting all have their left-turn signals on (well, the ones that bothered to signal).

I really dislike some of the externalities created by waze.

This is easy to fix, you report a map problem in Waze and then follow up on a computer and mark that this turn only allows turning right. If needed you can provide this picture.

I already fixed several intersections this way.

That's assuming the problem is indeed with Waze and is not just asshole drivers. When I am in scenario when Waze made me make an illegal turn I report the map issue, turn the way sign suggests and wait for Waze to come up with a new route, so I'm surprised that no one did this yet in your area.

What's the intersection?

I think it may be fixed now but drivers were making left turns from there (SE 6th and Tacoma, Portland, OR) for months. The left turn there is only for cyclists and when the cars stacked up it made for very sketchy biking. As for me having the responsibility of fixing bad directions, that’s exactly (part of) the externality I’m objecting to. Why, as a resident of that neighborhood is it my job to help fix it?
