That in no way resembles his work experience. He did tell me a few interesting things, though. He was really surprised how many software devs he met who were driving the big rigs. It seems to be a thing.
Another was how many skills overlap the two fields. Driving the big rig is an exercise in resource management and planning, so you can do things like ensure that by the time you need more fuel, you're in a place where the fuel costs are lower.
There is one stereotype that he confirmed, though: it's common for drivers to keep two sets of driving logs, one real and one doctored, in order to be able to drive longer at a time than is legally allowed without getting caught.
This was quite a number of years ago, though. It's entirely possible that GPS is used to mitigate this these days. I don't know.
