Re: Why not a cargo version
. Often customers are willing to pay for speed of delivery, especially with JIT manufacturing.
JIT means they are willing to pay for reliability.
That's why Maersk's new container ships are half the speed of the last lot. So long as I can promise to the hour when the parts arrive then you don't care if it is in 10 days or 20 - it's just a longer conveyor. The extra cost of capital tied up in the parts is so low that the cost savings on fuel win.
It's only for one offs or launch day spikes of a new iPhone that you need rapid delivery.
