I have no direct knowledge of this topic, however highway robbery is older than civilization! After watching some documentary episode about trucking in New Guinea, and watching lines of trucks dutifully entering scales in California with literally dozens of cameras and connected tracking info databases.. I suspect that there is a clear spectrum around every single major truck route around the world (minus Japan perhaps).

I'd believe it's as old. It seems like it'd be difficult for it to be older, though - why is someone moving along a highway if there are no civilizations?
