Just spitballing but it seems a unique aspect of a human driver is their fear for loss of life. We're all subtly terrified we are about to die and that keeps us sharp and responsive and thoughtful while driving.

#13Many cars monitor rotational speed of the tires in order to determine whether a wheel is slipping. A Model 3 can detect whether a tire is new or old based on tread depth, something I learned the hard way.
If trucks were outfitted with rotational encoders on all tires, 'slipperiness' could be monitored periodically by, for example, tapping brakes and checking whether all wheels continue to rotate at the same speed. In emergency braking or maneuvering, the rotational speed of all tires can be input to the recovery algorithm to perform braking. If the brakes are independently controlled, this can be performed per wheel.
More generally, trucks run in fleets and on routes. Similar to aircraft reporting turbulence so the next craft can adjust, trucks can report road conditions so that approaching trucks can adjust their speed or pull over completely if conditions are so bad.

#14It would be interesting to hear what a company like Aurora and their backers were thinking back in 2020. It seems unlikely that they did not come up with these arguments themselves, so what were the counterarguments?

#16Stop the truck using a couple of vehicles, cut open the lock on the rear doors, and loot. Pick an isolated stretch of toad, and the pirates will be gone before anyone can respond.

#19There are a lot of differences between passenger vehicles and trucks. The physical dynamics of articulated vehicles, the mission profile, and social dynamics come to mind. How does a robotruck place cones or flares while it awaits rescue?
Personally, I expect autonomous trucking to be a force-multiplier for humans who were formerly drivers. Such trucks will have sleeper cabs and the human will be there to maintain the vehicle and handle the long tail of tasks (filling tires, cleaning, refueling, repairs, rigging, whatever). You'll get 24-hour operation out of a single human employee because they'll be able to sleep and do other things most of the time. Maybe they'll work a second job as a remote call-center operator.

#20- Sensing distance is a good one for sure. At the same time, it's for now a technical issue. So that a viable temporary progress-making solution might be to have an additional vehicle in the autonomous system: a sensing car is in front, and one or more semi-trucks follow. Then the autonomous system far out-senses a human driver. And we get progress even if the cost-proposition becomes a little harder.
But otherwise:
- Nominal stopping distance as shown include 2.5 seconds of reaction time - fair for a human driver perhaps but hopefully the machine gains a lot of space there.
- "Stopping in lane" is as insane in the city as it is on a freeway. We can't seriously consider that a long term solution in the city? Less risk temporarily okay but not a serious solution. (But fair point on this one: if all else fails it is, for now, an option in the city).
- Even for humans, driving on the freeway is not a question of perfect judgement. It is about quickly but calmly picking a reasonable solution. Including, in doubt, moving to a safer lane and slowing down while measuring the risk of rear-ending. Nobody asks a human to completely eliminate the risk of rear-ending. That sounds within the range of what software can do?
- Jack-knifing and other complex behaviors are probably far better suited to computing solutions - which can sense far more measurements than the humans, independently actuate more control points, and compute actually more or less complete solutions when the human is seat-of-the-pants -ing in real time (with dubious real life record too - see brutal and fatal). Simple no, but all that hard to beat the human sounds absurd (anyone with more input on this?) See for example the drift-parallel-parking stunts achieved with cars. We may not yet be at drift-parallel-parking semi-trucks but anyone here doubts that this is achievable?
- Ease and quantity of samples might be a better point. Waymo really got on it and accumulated a lot of driving data. But then also, most of that data by now is city driving.
- Will trucks happen before cars? Well, cars are already there so... already answered.
