Well I hope giving that 3 makes you feel really good about yourself when the guy did his job and you're just hurting him for it. You know how they are judged and you do it anyway out of some misguided notion of what the rating system _should_ be and an insatiable urge to always be "right".
My comment was intended to point out that the rating system is inherently dishonest. It was not intended to indicate what I would or wouldn't do when rating.
From reading the comments here, though, I think I know what I'll do: opt out of the whole thing and avoid ride-sharing services in the future.
It's a dishonest rating when you know that a 5 means normal experience. Then you are just making a point. There is a time and a place to make a point, but for stuff like tipping and star ratings policy changes are the best course of action; not hanging individuals out to dry. If your the only person not leaving somebody tips(and I hate tipping) or giving them 3 stars you're not changing the system, you are just being an asshole.
EDIT: I mean the royal "you", not you specifically. Also, I have been the a'hole before :|

I agree, in a sense. If you're working with a rating system that is inherently dishonest (as I just learned this one is) by redefining what ratings mean, then it's dishonest to supply a rating that you know means something other than what it should.
