If you've used ridesharing often enough, you've probably run into problems getting the driver to pick you up at just the right spot. Ever play a frantic game of phone tag as the driver circles the block looking for you? Mercifully, that might not be much of an issue in the near future. Uber is partnering with Foursquare to use the location-based service's data to improve the accuracy of pickups and dropoffs. It'll tweak Foursquare's point-of-interest info to show drivers where to go when you request a ride or a bite to eat. It may indicate where the front entrance is, for example, or tell UberEats drivers to stop near the side door.
