Hitting the road, without humans.
2016 brought several advancements in self-driving technology. While most cars on the road are still driven by human beings, more and more vehicles are going autonomous. For example, Google's fleet of self-driving cars hit 2 million miles on the road.
Another automaker, Tesla, released a software update that overnight turned traditional cars into semi-autonomous ones. While it was a big advancement, it was not risk free: In July, a crash of a Tesla Model S with autopilot led to a driver fatality.
Meanwhile, ride-hailing service Uber began testing its own autonomous cars in Pittsburgh and purchased Otto, a company that developed the first self-driving trucks. In October, one big rig ran 50,000 cans of beer across Colorado without a human driver.
