Earlier quoted context omitted.
> Why do you think a trucker would risk life or even their truck in a highway robbery? That's an armed robbery whereas stealing from a robo-truck is more like breaking and entering. Robberies require the willingness and ability to commit violence. Having a human witness present means more risk of things going wrong, even if they don't intervene. I think all these factors prevent a lot of potential crimes.
These trucks are already covered in cameras. The self driving ones even more. How does this highway robbery even work? You force the autonomous truck to stop, take an angle grinder to the doors, then... unpack all the crates and boxes and hope you find something good that's also small enough to get away with? it just doesn't pass the sniff test for me.
If you ask truckers they'll probably say something about blue lights and asking to see license and registration.
