If I had to bet, that's the way I see it playing out. In the states, many distribution centers are located next to major transportation arteries, whether rail or interstate highway. In addition, many of the places they ship to are also located on major arteries. It wouldn't be a huge stretch to have automated trucks you load on one end, they drive to the other (using 98% highway driving), then park in a waiting area until a human finishes the job by parking them. The interesting edge cases here would be accidents, construction, and detours. Whatever you deploy should be able to handle those without human intervention. Otherwise we could end up with every accident site also having 100 automated trucks at a dead stop waiting on drivers to show up. That'd be ugly.
