It's no secret that Amazon is taking increasing control of its delivery chain, whether it's buying its own jets or managing ocean freight -- anything to lower costs and ship your goods a little bit faster. Autonomous vehicles are a logical extension of that. If it reduced the need for human drivers, delivery trucks could operate almost non-stop. This would sadly eliminate jobs, but it could also mean getting that big Amazon Prime order in one day versus two.

And to some extent, research into autonomous tech might be necessary for Amazon's drone delivery plans -- that's still the company's big focus, according to the tipsters. While there aren't specific details, Amazon may "coordinate" drones with ground-based self-driving vehicles (say, vans that double as launchpads) to help with deliveries. The driverless team may have a lot of work to do, but there could be a day where your Amazon purchases are handled almost exclusively by machines.
