I agree completely. A binary yes/no would be a lot more useful in gauging customer satisfaction with drivers. When 5 stars is "yes" and 1-4 stars are "no," Uber forsakes the gradient system that, as far as I can tell, is the only merit of star rankings. That said... Amazon has likewise mutated star rankings. What was the statistic, that 80% of Amazon's products have a 4-5 star ranking? For any given listing, 5 stars indicates satisfaction, 4 stars indicates likely problems, and 3 stars indicates serious defects. I've never seen 1 or 2 star reviews except on long-tail products with less than a handful of reviews. Despite turning star rankings into blunt instruments, Amazon still features probably the most valuable, extensive reviews on the internet.
