Would it still be an advanced net if you had humans in the trucks as a &#x27;backup&#x27;, with the autonomous driving doing 90% of the &#x27;boring&#x27; driving down the highways? Humans would still drive the last mile (ha!).<p>Would that be significant safer and more efficient to make it worthwhile?<p>If you limit autonomous driving to the main freight routes on the highway, I can see self driving vehicles happening a lot sooner than I previously expected. Like 20 years sooner.
