On one hand, this is an obvious use case for the technology. Not only it might remove the most boring — and therefore dangerous — part of the work, it could also save a lot of gas thanks to the use of "road trains" created by multiple trucks following each other closely.

And when there is already a lack of drivers, who'd want to start on the business when you're guaranteed to be made redundant in a decade or two?
