Uber is making mainstream customer rating. It will change human interactions drastically

Uber staff rate customers. They don't hide it. They want customers to know it.
Some drivers event propose to trade a 5 star to you vs. a 5 star for them. 
The fear of getting a 1 star make drivers ultra polite.
And what about you knowing you're rated?
Of course, you don't behave like a "rated version of you a lot nicer" in Uber car. 
Of course... It's well known that rating and judgment don't change behavior.

It will be a lot of fun when every interaction we'll have will mean a mutual rating and we'll all have scores. Better not be too rude...
