Doing something about "those people" is a common refrain when justifying poor ideas.
If the system were such that drivers would only leave negative feedback on exceptionally bad encounters, with a specifically described complaint, it could plausibly work as you state.
But as it stands, your "shitty human being" is likely to not be correlated with a poor average rating - imagine a run of the mill douchebag that talks themselves up to everyone they meet, yet is an abusive asshole when it benefits them. Such a person is likely to have a higher passenger rating than a genuinely nice person who is socially awkward.
All systems calcify, become overprescriptive, and get gamed by people with nothing better to do. This setup is ripe for that, and Uber's / Surveillance Valley's general stance towards accountability doubles the worry.
