50 hours? Can this truck fuel itself? Inspect its load? React to a load that becomes unsecure mid route? How about when the truck is pulled over for an inspection? How will it deal with a stowaway? Brake inspection before a big hill? All the rare events add up to significant barriers to actually removing the human from the truck.

> Can this truck fuel itself?

Who cares? That's how trucks are different. Somebody at the company just calls the fuel station and say "Hey, I want to refuel my trucks there, when they get there, you refuel them, and I pay you at the end of the week. Deal?"

> React to a load that becomes unsecure mid route?

How common is that? You basically have the truck phone home and send somebody there to solve the issue. Depending on the likelihood it can be a major cost by hiring people every so distance, or a delay you just deal with to something that is solved by dispatching people by plane.

> How will it deal with a stowaway?

Most likely, it won't.

> Brake inspection before a big hill?

By braking and checking the acceleration, just like a human. In two axes and paying attention to frequency responses, what a human can't do.

First off, how do you detect a load that has become unsecured? I saw bees on a flatbed getting hauled. How do you detect that the net is no longer tied down securely besides looking at it occasionally.

Hauling livestock is one of those difficult hauling items. If you accelerate or decelerate too fast, they die.

Or how about the tale of the worst load ever - Oregon Potato Chips to Texas ( https://www.dat.com/blog/post/my-worst-load-ever-hauling-ore... ). While that one has a "ok, this needs to be another factor in the routing" - local barometric pressure could cause a problem.

Brake inspections are likely less of an issue than chains for that storm that just hit. The storm that dumps a foot of snow on I80 over the Sierras. That's not too much - but everything needs to chain up unless its a 4 wheel drive pickup trick. That includes the semis.

Or a wind advisory over the Mackinac bridge ( https://www.channel3000.com/news/mackinac-bridge-partially-c... )

> The bridge that typically enables travelers to pass over the Straits of Mackinac has been closed to all vehicles except passenger cars, passenger vans and empty pickup trucks, authorities said.

> Motorists permitted to travel across are advised to reduce speeds to 20 miles per hour and to be prepared to stop.

And your robot just lost is license for not performing a proper pre-hill brake check. Large trucks are not cars.

Then look in this pdf for "En route inspections"

From Alberta:

A vehicle inspection at a rest and check stop should include the following: • All lights are clean and in working order. • There are no air leaks. • All the wheels are secure, and tires are properly inflated and are not hot. • There are no broken or loose items on the vehicle. • The load is secure. • The dangerous goods placards are clean and secure (if applicable). • The trailer locking mechanisms are secure and in good condition. • The brakes are properly adjusted.

These procedures assume human eyes. A robot might be able to tick all the boxes via sensors, but that isn't going to be enough to constitute due care when something goes wrong.

Ok then, same as with the refueling example: Contract that out to the personnel at the truck stop.

Checks are needed ever 3 hours. So if you are stuck in traffic you might have to do them every few miles

In winter, does the truck put on chains before the pass and take them off on the other side?
