This is fantastic. If the markups are high enough, I can imagine people who have the job of just taking uber rides all day to grind up ratings for good passenger uber accounts. Reminiscent of faction grinding in MMOs. Life imitates art.

Well, we already gamified exercise and productivity, why not gamify social status and access to services!

So I call in and ask to have a high-rated account summon an Uber to my location. Of course it would make sense to centralize this. Congratulations, we've reinvented taxi dispatch.

That will be easily detectable by Uber

Maybe or maybe not. If it is then it will just kick off an arms race.

Although, if Uber really knows what they're doing, then they'll allow the buying and selling of accounts and then take a percentage of the sale.

Never underestimate the power of a market to make something come about.
