“Hell” was devised to monitor the locations of all Uber drivers who also drove for Lyft. Uber employees at headquarters would create fake Lyft accounts, which tracked nearby vehicles—up to eight per fake account. Information about those vehicles was then sent back to Uber and stored in a database. “Hell” created a way for Uber to monitor the real-time positions of Lyft drivers. And because many of those drivers worked for Uber as well, Uber could monitor the rates Lyft was offering for drivers and outbid them, thereby swaying drivers to work more regularly for Uber.
