The McDonald’s on Jalan Salemba Raya, Jakarta’s crowded main thoroughfare, is a magnet for food delivery orders. On any given day, a dozen or so app-based delivery drivers—locally called ojol—wait in the parking lot. Inch by inch, they try to move as close as they can to the center of the lot, desperate to have the matching algorithms recognize their proximity and assign them an order. 

But even more drivers are there virtually, using GPS-spoofing apps to position themselves right in the center of the McDonald's lot while they physically wait under nearby shelters. Using these unofficial apps, known as tuyul, drivers can set their GPS pins at the optimal location they would like orders from, without having to physically drive there.
