    The article features a truck that the chips get loaded onto. This quote from Tanenbaum immediately jumped into mind:

    "Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway."

      I was wondering how much financial value they put in one truck. Presumably the value density of this stuff is incredibly high (although not really to anyone else, so security probably isn't a huge issue). At what point do you split the shipment between multiple trucks to avoid huge losses if there's a crash?

      When I worked on satellites we had some electronics which used a radiation hardened FPGA which cost something like $500k per chip. Carrying that around was nerve wracking.

        It's treated the same way as any other generic shipment of cargo, really. It's fine throwing $20 million in one truck.

        Security is an issue, though, these are treated as a high value load and typically would be followed by unmarked, plain clothes armed security guards tailing around the truck. (That's how Apple often does warehouse deliveries of trucks full of iPhones. It wouldn't surprise me if there was going to be some rolling lead soon following some trucks full of Duos...)
