You seem to be changing focus. Op is pointing out that 10k fruit transported has a very low amortized cost per piece, whereas driving to the store has a low number of goods to amortize over.

This was pointed out on a freakanomics episode.

Furthermore last I checked the academic analysis I could find found that Amazon prime delivery has smaller footprint than driving to the store unless you’re getting like 14 items at once for similar reasons.
