It’s called SPOT and involves drivers installing a colored LED light on the windshield. While the passenger is waiting to be picked up, they can tap a colored button (yellow, orange, pink, purple, blue, or green), and then look for the Uber with the matching colored SPOT light. Passengers can even hold down on one of the buttons to turn their phone that color and wave it in the air to help their driver find them. This way, passengers won’t accidentally open the door of the wrong Uber, or even a non-Uber civilian’s car, which I can attest is quite awkward. Previously, passengers had to rely on Uber’s sometimes-laggy map, generic car types, and hard-to-read license plates.
