I wouldn't trust the app not to have something built in that could limit job offers after you've completed 13/14 jobs.It's just a computer program.Easily manipulated.If they can push jobs towards Gold and ambassador drivers they can also manipulate the work when bonuses are in play.
Keep in mind the parent group Daimler and BMW is getting hammered by all the diesel scandals.Sales are way down in the last two years.Don't think they'd be handing out money for nothing to a few Prius driving taxi drivers.
