The Freightliner Inspiration is an autonomous truck that was recently licensed to operate on public highways in the state of Nevada. This hauler can be fully controlled by an onboard computer under proper traffic and environmental conditions.
The truck uses a complex combination of cameras and radar technology to stay stable on the lanes and also to avoid collisions, moderate speed, brake and steer. A stereo camera is capable of recognizing road markings.
The incorporation of autonomous technology into freight trucks simply makes good sense because these haulers spend most of their time on freeways and highways, so it makes sense to relieve human drivers of tedious long-haul driving and allow them to engage in other tasks.
