The accident rate isn't even the biggest advantage over human drivers.

The big game changer is that the computer doesn't need sleep!!

Human truck drivers in the US are only legally allowed to drive 10-12 hours per day. Which usually means the truck is parked half the time. With a computer driving, trucks can run non stop 24/7.

This is revolutionary change! Twice the delivery speed at half the cost. Should improve a lot of things across the economy. Unless some luddites find the power to stop it.

> How will this affect transportation jobs?

The human long distance truck driver will fade away as a career. It will probably take a decade or two, so people will have time to adjust.

The transportation industry should end up substantially larger, which normally creates a bunch of new jobs/professions, but I won't pretend to know how that will play out.
