You don't get to pick your driver, so the driver ratings really don't matter to any particular user for a given ride.
IMO the driver ratings make sense, and give the driver incentive to not take purposefully long routes, to not ignore your requests to adjust the A/C, to not talk on their phone, etc.
I have been in countless cab riders where it is clear the driver does not care at all what you think about the ride or the overall experience, and they know you can't really do anything about it (other than maybe not tip them).
