There’s no reason for it to be all or none. Doesn’t matter if the people are slower, collision avoidance is collision avoidance, the methods are the same, and having one side react faster just makes the accident easier to avoid. And frankly the way moving cars respond to input negates most of the computer’s “advantage”.
Machines do grey just fine. People won’t die, they’ll live because the computer driven cars will be better than the human driven cars at not killing people.
Blowouts and breakdowns will be handled the same by a computer as a person, pull over and stop, it ain’t complicated. We already HAVE the tech IN cars right now to do this, the delay right now is our laws and acceptance.
I drive/own a propane transport. Someday it might be automated, but the accidents involving the handling of explosive gases will be spectacular during the transition.
Some tasks require more sensors and handshakes between systems than the human costs in the long run.
Not to mention maneuvering a 53’ trailer which is essentially a bomb into places like orchards or small retail locations.
Line haul of freight? No problem! Bulk hazmat? No way.
