>>Do I want to walk down the road with drones dodging around me . No.
My understanding is that the drones will fly at between 200 and 400 feet. Presumably not a lot different from crows flying around the place.
>>Also the self driving truck trains. Great idea but what about all the non self driving cars around them and why not put that freight where it belongs. On rails.
Not everybody agrees, E.g.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
