I'm not sure the whole story has been told re: the driver with the laptop.
I used to work in fruit and veg. Many a time I've heard our Operations Director or Senior Buyer screaming "I don't care what it takes, get the fruit to me by 8am tomorrow for packing or we reject the lot" to a Spanish or Italian supplier. This inevitably meant some knackered driver being told to go out of hours and make sure the produce was delivered. The companies don't care as if the driver is stopped, he'll be sanctioned. The managers behind him who are telling him to deliver it on time or he'll lose his job, and the people behind them, are never in the firing line.
So while this driver undeniably killed people because he was checking his laptop, he may have been told that if he didn't check it, he'd lose his job. To me, that makes the managers culpable too.
