I think they should start putting reusable GPS-devices on the packages (at a small fee, of course). That way you could see were your package REALLY is. That would be a big step up from the current system. They could make it so that they're like a little nodes that attach to the package, then when they deliver it to you, they just detach it perhaps and use it for another package, kind of like they do with those plastic security tags that are on the new clothing in department stores.
