I've noticed that sometimes the JNF script will actually 'fix' the terminal node on a dead end even though the highlights scrip doesn't indicate anything's wrong. I think a self connected terminal node may cause, or at least allow, this type of route to come out of the server.
Nah, its just that dead end segments are the only place Waze officially supports U-Turns. So if Waze wants the user to go back the other direction, and there's no "around the block" routes it can give them, it sends them to the closest dead end to turn around.
The problem with this system generated UR, is it will only show 2 segments of the route. The segments before and after the turn. Waze just wants us to double check that the turn is properly allowed, not to troubleshoot the entire route. So if it is allowed, and it looks like a dead end u-turn, mark as solved. If it looks like it is allowed, and its not a dead end u-turn, you might want to scan ahead to see if there's anything else wonky going on at the next few junctions to cause Waze to want to turn someone too early. But with only 2 segments of the route, and no idea where they are going its often impossible to know why Waze gave the turn direction and why drivers ignored it.
