To answer my initial question: No. Hell no. Uber One is trash.
This month, they switched me from a 5% Uber One discount on rides to a 6% rebate of uber cash on rides. Well, I noticed that at least two rides didn't credit any sort of uber cash. The idiots at their outsourced customer service couldn't grasp the issue.
I just ended my membership. Uber One, whether by incompetence or malice, is a scam.
