Agreed on your first point of volume and we're not given enough detail around 2 separate and only tangentially related metrics to make any real conclusions. That said; I did consider this briefly but even then the math to make that work still seems extreme. Are Amazon packages making up that much of our parcel these days? 3-to-1 or 5-to-1 would certainly change the economics for this to make more sense, but are they truly responsible for 75%-85% of all parcels these days? Even if we select for residential only I feel like that is super high.
Then again my monkey brain sucks at statistics and considering the last year or so of my own home usage it is probably close to 1-to-1. And we try to avoid Amazon. So probably a lot closer to those numbers above than I'm comfortable to admit.
