Not under immediate threat, true. But it’ll be a gradual process over 15-20 years, and short-haul and long-haul driving jobs are going to be gone one way or another once issues like the “snow problem” are sorted out. The capitalist impulse to reduce human labour costs is a strong impetus, and there are many companies working to make it happen.
Like non-commerical drivers over that period, they’ll have less and less to do in terms of driving as automation features are slowly and subtly phased in. Just about all the non-driving tasks listed will either be automated (e.g. maintaining logs, navigating) or done at the depots and garages by a much smaller on-site staff (e.g. inspections, safety checks). For short-haul you’ll also see a lot more robot vehicles and drones.
Right before the end the humans will be in the cab as essentially rent-a-cops, and guard labour will officially replace truck driving as the most common job for any American with a high school diploma or less. If a UBI isn’t in place at that point this country is in for a rough time.
