As someone who has lived most of their life in rural America, I doubt it. Too many variables including unforeseen situations. Hijacking is one. Once a crew has spotted a computer driven truck, all they need to do is actuate the trailer brakes. The system will shut down due to an unsafe condition allowing the crew access to the cargo. Insurance companies will not be amused. Trucking companies go out of their way to minimize costs. There are many times when a human driver can save money.

Excellent point. The hijacking potential could mean that trucking concerns may well spend the money they thought they were saving on personnel costs (or even more) on insurance premiums. While it's not that easy to hijack an 18-wheeler now with human drivers, once they're all automated, it will become so easy that high school kids will be doing it for their own amusement.
