I get mediocre ratings from drivers when I take a shared ride and don't tip. Rating passengers poorly for not tipping is broken functionality, we really need self-driving cars and no drivers. Historically I've always given drivers 5 stars, but now whenever I see my rating dip I one star all my recent rides since Uber won't tell me which driver did it. The less meaningful the broken rating system is the better.
