Consider those that rate drivers: 1. Drunks 2. Emotional and disturbed persons 3. Jealous because we have what they want 4. Addicts of some sort 5. No drivers license - suspended or revoked 6. Those that think they are "privileged" and order a Pool and expect service like a Limo. My guess is that about 1/4 of Uber pax fall into the above categories.
