First Road Legal Big Rig That Can Drive Itself

Last night at the Hoover Dam, Freightliner unveiled the Inspiration Truck — a partially autonomous big rig that could save lives, mitigate driver fatigue and stress, and reduce CO2 emissions up to 5 percent. Daimler, which owns Freightliner, says it has done more than 10,000 miles of testing on the truck. And now it's street-legal, having been officially granted one of Nevada's "Autonomous Vehicle" license plates (the first for a commercial truck) by Nevada governor Brian Sandoval at a media event before the unveiling.  The Inspiration Truck and Daimler's underlying "Highway Pilot" technology isn't meant to replace truck drivers completely. Instead, it's meant to solve the problem of fatigued driving, something that plagues truck drivers who have to pull long shifts. According to Daimler, 90 percent of truck crashes result from driver error, and in one out of every eight of those cases driver fatigue plays a role.
