The Driverless Future Won't Start with Cars

Self-driving cars are coming.

Tesla is aiming to have a fully driverless car ready by 2018, and Uber recently kicked off a pilot in Pittsburgh where select users can hail a ride in a self-driving car. And many other companies have plans to roll out some form of self-driving cars by 2020.

But chances are, you're more likely to see a driverless truck in practice before a self-driving car.
