Apple and Alphabet aren't the only tech heavyweights branching out into self-driving vehicle technology. Amazon wants in on the action, too. Wall Street Journal sources hear that Amazon formed a small (roughly 12 people) team about a year ago to explore the possibilities of autonomous vehicles. This doesn't guarantee you'll see Amazon-made driverless vans roaming the streets, to be clear. Rather, the group is an "in-house think tank" looking at ways to take advantage of self-driving tech for the company's online shopping business. With that said, smarter delivery vehicles are a real possibility.
