With this type of automatic error, you need to check further down the route the user(s) did take as another turn (or series of turns) they took could be incorrect, or even segments with the wrong direction.
I've found having solved a couple dozen of these that it's more useful checking the route Waze wanted
a user to take, although checking both is valuable.
Checking the user's route will give you a sense for where most people go when they think they know better - and in a situation like this, sometimes they do! And, as the OP said, you can find turn restrictions at the intersection or a bit down the road on the green routes...
Checking Waze's purple route though can take a little more digging, but in my own experience I'm finding that more than 50% - maybe even 75% of the time, there's a problem a short distance away from the intersection (3-5 segments) that explains Waze's choice. Often the UR will only have the first segment or two's instructions in the error...which isn't a HUGE problem; it just means that usually you'll be looking in 'the neighborhood you were pointed into'. In those situations, I've seen things like this in the purple segment directions:
* Neighborhoods Waze wants to go into (to cut off distance), with a 'Dead end' sign that, while they had other ways in and out than the one, clearly they're not meant to be used that way (think 'two track dirt road or other clearly 'not streets'), which I marked as 'parking lot roads'.
* U-turn possibilities that are really just somebody's driveway (I delete those if they're short stubs)
* Streets Waze wants to use marked as two-way but actually one way
* Speed gone to hyperspeed plaid on a segment inside Waze's choice, meaning it's favoring it because of a bad segment
That said, it'd be useful if these URs could show...how to explain...purple routes the same way it's showing the green ones, maybe 3 segments out. Then we can see if Waze is always pointing in one single direction, or if it's just going 'wherever' after that.
