Trucking won't disappear overnight.
Automation makes sense for long haul highways, so truck drivers will shift to being last mile drivers.
Once there's enough driverless vehicles large trucks can signal smaller vehicles things like "I need to turn right so please leave me room in the left turn lane to my right". Frankly the tow truck industry needs some disrupting. At least here in Houston they are the most dangerous lawless drivers on the road and need to go.
Lots of industries and jobs pretty much disappeared overnight -- it took centuries or millennia for that to happen in the past.
It might not disappear overnight but it sure as hell isn't going to take 150 years!
Humans also have a tendency to always think "it'll stay the same as is right now".
