Uber's purchase of Otto provided the ride-sharing company with a beachhead to get into the trucking business, an entrée to the autonomous car industry and a bit of controversy. The resulting Uber Freight was announced last year, and the service intended to help truck drivers connect with cargo officially launched this May. The current business — so far focused in Texas — will expand to "major metros" across California, Arizona, Chicago, Georgia and both North and South Carolina in the next few months. The company says that these routes cover more than a quarter of the US drivers and freight. Uber has also updated its driver app to learn drivers' preferences and load history to notify them more quickly.
