Rails are indeed one of the cheapest, best scaling, and most reliable ways to move goods no doubt, but it also has a last mile problem.
Just wanted to point out the solution isn’t as easy as “rails all things”. Trucks still do offer some situational advantages, and will still have their place in logistics.
Fair response. It’s likely due to the lack of rail infrastructure why this delivery was “across the country”. Rails are typically much cheaper per ton-mile than trucks. If a rail alternative existed, I’m fairly certain the economics would have forced the use of trains.
However, I’d say the self driving part is still be a benefit that would improve truck utilization rate.
