One thing that bothers me is that, as a passenger, I can't see how the driver rated me. I can get my aggregate score from Uber, but not individual ride scores, while, I believe, drivers can get individual passenger scores. I'd be interested to see how drivers rate me, as a source of feedback.

Better system would be for both pax and driver to see how they were rated, but neither be able to see the rating until both have submitted their rating (to eliminate retaliation).
