But they probably sell your marketing data so if this guy, the driver, was previously googling football (soccer) gear, and now Uber has a record of your phones being in proximity for 10 minutes, now they will add your info to a list of people interested in football (soccer) gear by association, and Uber can reap a reward by selling this info to ad companies. But track down a bad driver??? Oh no, can’t do that.
