I used to work for a company that made long-life self-contained GPS locators, for commercial asset tracking. I remember how much we chortled ironically when a shipment of our devices was literally stolen by a hapless meth addict who noticed keys left in the ignition.

Everyone was laughing because "ha, that idiot stole a thousand GPS trackers, he's the most tracked criminal ever!" But of course every single one of those trackers was in sleep mode, and the only tracking bug was not part of the shipment. Sure, he was caught red-handed within half an hour while a police dispatcher watched a moving dot on a google map, but he was only being tracked by a single device, and we had no way to remote-active the other thousand.

Just an amusing related anecdote.

Set fire to the truck after you rob it to destroy any on-board evidence (like hard drives containing surveillance footage), only commit crimes in a wireless dead zone so no data is transmitted outside (or better yet, use a police stingray so you can do it anywhere), and put all cargo inside a faraday cage. Also I'm not sure there's any reason to believe those kind of security measures wouldn't already exist for a manned truck if the goods are expensive enough, so really it's the benefit of not having to deal with a person.

I'd much rather do all that than kill an armed truck driver.

Now that I actually am thinking about this more, I'd just get a sniper rifle and shoot the sensor units on the truck so it would be incapable of driving further (as opposed to throwing a mattress onto the road).

But again, I'm not in the business of robbing trucks. I'm just saying I'd rather rob a robot than a person. I doubt robberies are a big concern for driverless trucks.

Life isn't like a movie. Anyone who has the knowledge (of the vehicle and its surveillance systems, the schedule, the cargo onboard...) and the capability (skills and resources) to pull off what you're suggesting has plenty of lucrative legal opportunities. And any cargo load valuable enough to make a Hollywood-style heist actually worthwhile would be transported by more secure means.

It doesn't take that much skill to know that a certain stretch of road doesn't have cell signal and how to set fire to a truck. It takes even less skill when you know there's no human on the truck to stop you

It may or may not work, but I have no doubt that someone will try.

> Set fire to the truck after you rob it to destroy any on-board evidence

Trucks are big. They're also not particularly flammable. Hard drives are small and easy to fireproof.

> only commit crimes in a wireless dead zone so no data is transmitted outside

This put you pretty far out of your way, and you're eventually going to have to bring a truckload of goods back from the middle of Idaho or wherever. Plus, trucks can carry pretty big antenna.

> (or better yet, use a police stingray so you can do it anywhere)

This doesn't really work that way, and also this is an additional major crime. Plus, people are looking for these.

> and put all cargo inside a faraday cage

That's a big faraday cage. Plus, what happens when you have to take the cargo out of your truck-sized theft apparatus and fence it?

> I'd just get a sniper rifle and shoot the sensor units on the truck so it would be incapable of driving further

I doubt there's anyone on earth who could make that shot once, much less 5+ times in a few seconds. A truck is moving 60+ MPH and the target is a few inches across.

As soon as low orbit satellite internet services like Starlink are operational then you'll be out of luck, there won't be any more dead zones.

Also, every 10th truck probably has a guy with a shotgun in the back.

More to the point, I think if we're trying to secure the use case of "truck the same as it has been for 30 years gets a black box put in it" we're doing it wrong. After not too long you just flat out won't be able to get in, even if you do stop the truck from moving. You won't be able to drive it anywhere - what need is there for a cab on an auto-truck?
