I got this in my eMail today regarding autonomous trucks. Not a concept, they are apparently on the road already in a small part of Nevada. Can only run autonomously with a driver behind the wheel, in daylight, and in clear weather.
First Autonomous Trucks
I can see a need for it but it seems like they missed a big part of situational awareness by just having radar pointing forward. and is it really a good idea to have an inattentive driver in what could be an 80k+ lb truck. I don't know. I guess if it works.
