Actually, the complaint in California is in the guardian article linked and has Uber doing the turn illegaly in CA.
That said, the guardian article is a year old, while the Pittsburgh complaint is from today and describes legal behavior in CA.
Basically, Uber probably changed their software's behavior to follow California law following the complaints last year and that is now resulting in complaints in Pittsburgh.
I have no clue what PA law is on this, but I can imagine the law may differ depending on jurisdictions and this would be something where engineers will have to have a variety of behaviors depending on the applicable law.
I have suggested many times that the things computers are good at include looking up inconsistent rules in a database, so this doesn't seem as if it should be an either-or issue for the car, it should know all the rules and be able to follow them as appropriate, where a human might be forgetful.
