Popular cab-hailing app Uber has launched a new feature called Express Pool. In the Uber Express Pool service, when commuters hail a cab, they will be asked to walk to a nearby spot or wait a few minutes before the trip starts. It will work in the same way while dropping off. This brings down the fare by a significant amount. Uber elaborated on its Help page saying, "Spots change based on popular routes at the time you request. You'll see walking directions to the best spot."
