ARMIN SAMII HAD been biking for UberEats for a few weeks last July when he accepted a delivery he estimated would take 20 minutes, tops. But the app led him up one of the steepest hills in Pittsburgh, a 4-mile one-way trip that clocked in at an hour. Then he noticed that Uber had only paid him for 1 mile—the distance between his origin and destination as the crow flies, but not as the man bikes.
