Those cars you see in your area on the map when you open Uber might not be there at all.
At best case, the map that seems to show how many drivers are in your neighborhood appears to be really inaccurate. Worst case, the map is nothing more than a "screen saver" that represents absolutely nothing at all, according to an investigation published on Motherboard.
While the report stops far from offering a definitive answer as to whether the map is total B.S., it does quote a surprising email from an Uber Help staffer:
Why would Uber do this? Some have speculated that people are more likely to go through with using Uber if they think there are many drivers nearby.
That could explain why the "phantom cars" appear to be so close to your pin on the map, but your wait time is so long for a driver to arrive.
An official spokesperson for Uber, however, told Motherboard that the map is generally accurate. Go figure.
