The Freightliner Inspiration is the world’s first road-ready self-driving truck, and Daimler let us take a ride in one outside Las Vegas Motor Speedway. Like with many other self-driving vehicles, the ride isn’t too exciting on the surface — that is, until you realize that a 20-ton machine is doing all the driving for you. You wont see these on the road any time soon, but they’ll bring a number of benefits when they get there. Self-driving trucks will cut down on emissions and save fuel. Most importantly, they will make the roads a safer place.
