AFAIK, TuSimple (http://www.tusimple.com/index-en.html) is much more mature on autonomous trucks. At least they have completed more road test. Last July, "TuSimple completed a 170-mile public road test from San Diego, California to Yuma, Arizona using its Level 4 system."

TuSimple has definitely been doing some great stuff. We did a similar test (w/freight) for the first time in January 2017...have have been doing that a lot over the last 15 months
