Correct me if I'm wrong, but how can they give you a 1-star rating? They don't know if I tipped or not as a rider, right? Isn't it all just added into their pay, no way to tell if a specific rider they had tipped X or Y? Or do they mean cash tips?

The driver's rating of a passenger can only be changed by opening a support ticket, not in the app (https://help.uber.com/partners/article/i-want-to-change-my-r...).
