Then why did you fail to mention them in your argument that automated trucks would cost more than the drivers? If you know the drivers cost more than $50,000 a year, then you should acknowledge that lest we think the rest of what you said is equally, er, unburdened with valid facts.
I think I recall that you drive an Acura that’s less than 15 years old. Nice car. I’ve got one myself.
What’s your yearly IT bill for it? Because a 3rd gen TL has more lines of computer code controlling it than an F-22 Raptor fighter plane, and by your logic you should be paying so much maintenance money on it just to keep the computers going that keeping a Veyron on the road would look cheap by comparison.
In short, like @MikeInNH said, we don’t need legions of computer techs to maintain systems anymore. There are very few cars with computer systems that require any sort of IT professionals to maintain it (and that number shrinks to nearly, if not zero if you eliminate military vehicles and supersonic land speed cars). Self-driving cars aren’t going to be any more maintenance-intensive from an IT standpoint than normal cars. It’s gonna be computer hardware, and lines of code, just like we have now, only more powerful.
