Interesting concept. Have to see how that shakes out. I think the way technology is going the autonomous truck will be commonplace by 2025, won’t need testing roadways at that point.
Why have 100 autonomous trucks all going the same route when you can put the materials on the back of on flatbed train?
Why invest in a concept which duplicates the functions of but is inferior to trains?
How about instead engaging in an intelligent alternative. .. like rolling back the punitive regulations and taxation which were implemented to make trucks competitive back before most of us on this forum were born?
Life is hard. It’s even harder when you’re stupid.
