Uber has yet to develop autonomous horn honking.
Imagine driving down the highway when you pass by an 18-wheeler with no one behind the wheel. That's exactly what's happening with Uber's latest project: self-driving trucks. Uber recently purchased San Francisco startup Otto, which takes traditional trucks and gives them a $30,000 retro-fit to make them autonomous.
The company made history recently by making the world's first autonomous delivery by truck. Beer—50,000 cans of it—was taken on a 120-mile trip in Colorado. While there was a driver on standby, he spent the 2-hour trip relaxing in the back.
To see the truck in action, check out the video below from Wired:
