Uber should offer "frequent rider miles"
Keeping up with the theme of miles from traveling frequently on airlines, Uber should offer frequent rider miles. Get a mile for each mile that you ride in an Uber. Redeem the miles for free rides and upgrades to Uber Black. Perhaps let someone who travels by Uber often redeem their miles to get a free ride when it's surging. Could offer "elite" status for riding so many miles in a year.
