<i>The two DoorDash drivers—Dashers, as the company calls them—are trying to persuade their peers to turn down the lowest-paying deliveries so the automated system for matching jobs with drivers will respond by raising pay rates.</i><p>When I drove for Uber, large groups of drivers would do this all the time. They'd coordinate online to stop taking fares at certain times of the day in order to drive the prices up.<p>Another thing they did: Whenever there was a big event in town where there was no way there would be enough drivers, they would set a time, and then all head to the airport staging parking lot for naps. They'd sit there until the map around the actual event turned all dark red, then head up there. By napping in the airport staging lot, they could avoid turning down fares, and avoid being penalized by Uber.<p>Another trick: Going to pick up a fare and deliberately parking behind a fence, or around the corner, or otherwise making yourself invisible to the rider, while looking like you were in the right place to the Uber app. Sit there for five minutes, then mark that the rider didn't show up and collect $5 for doing nothing.
