(Distance x Cost) / Pounds = Delivery Cost Per Pound
My point was that when you take into account the underlying economics, auto-pilot cars are an incremental improvement but not a major game changer. Self-driving cars don’t do all that much to change the outcome of various cost models because drivers are a relatively small part of the cost.
I had posited at the time that the only element of the equation which could really change the world would be making a pound weigh less than a pound. However, I was making the assumption that a mile would always be a mile. I was thinking two dimensionally. Yes, a mile is always a mile if you stay on the ground. But in the air, all bets are off.
The driver element is small but the mileage variable is huge. It’s every bit as crucial as weight.
Even though I don't think society will change very much with the advent of self-driving cars, bypassing roads for potentially shorter air routes could radically change some cost assumptions. But adding the air element introduces a whole new set of problems to solve.
