UPS, for several years now, gives you a stop-by-stop tracking GPS plot, once the package is 'in your area' or is under like 6 stops from you, whichever is greater (this is anecdotal from my tracking packages over the last decade+); basically the same as Amazon (but UPS had the ability first). FedEx is still window-only.

Maybe it's a region thing - I'm just a few miles from a large population center.
