A self-driving semi-tractor trailer has made its virgin journey across Colorado to deliver, what else, a load of beer.

In partnership with Anheuser-Busch, self-driving truck maker Otto said the driver of its 18-wheeler spent most of the 120-mile journey from Fort Collins to Colorado Springs viewing the road from the sleeper berth.

The truck hauled 51,744 cans of Budweiser down I-25 through downtown Denver on its way to Colorado Springs. Otto claimed it was the world’s first commercial shipment using a fully autonomous semi-trailer truck.
