Hopper says: The closer it gets to home, the slower it seems to travel.
He is right, and I suggest that this is true whatever the system you use to transmit goods or messages.
Even in the 'good old days' the steam train would bring the post at perhaps 40 mph, to the nearest town station. It would then be taken to the village post office by horse and cart – 10 mph max. From there the postman would walk to your door at 2 mph or less, delivering other stuff en route.
Such is life
