Amazon’s work in autonomous vehicles isn’t in the media spotlight the way its drone program is. At the end of 2016, Amazon began deploying delivery drones in the U.K. through its Amazon Prime Air initiative. As part of that program, Amazon has also leased a fleet of 40 branded airplanes. The company?bought thousands of truck trailers and even filed a patent for a system that would allow drones to hitch rides on trucks or buses.
