Uber will shut down its current version of UberRush, the logistics and courier delivery service it offered to businesses, Quartz reported Friday. The lesser-known Uber delivery service allowed restaurants and some other businesses to power their own deliveries. But as the popularity of UberEats, which allowed customers to order food directly through Uber grew, drivers who could have been picking up passengers were busy transporting meals through UberRush and UberEats. That led to surge pricing for UberX -- the actual service Uber customers depend on most.
