I think that ultimately you run into the same issue.

In US education you are taught that you need to get an A. Anything below a C, gets you on the equivalent of a “Performance Improvement Plan” in corporate world. And B is… well… B.

So with that rating engrained, people would probably feel bad about rating their ride-share driver a C when they did what was expected. And it wouldn’t stop companies from pushing for A ratings.

Even elsewhere like the food industry where they do have letter ratings, A is the norm with anything lower being an outlier.

Perhaps for this to work, it would need a complete systemic shift where C truly is the average and A and F are the outliers. In school C would need to be “did the student do the assignment.” And A would need to be “the student did the assignment, and then some.”
