Only one item can be delivered at a time. It can’t weigh more than 5 pounds. It can’t be too big. It can’t be something breakable, since the drone drops it from 12 feet. The drones can’t fly when it is too hot or too windy or too rainy.
You need to be home to put out the landing target and to make sure that a porch pirate doesn’t make off with your item or that it doesn’t roll into the street (which happened once to Lord and Silverman). But your car can’t be in the driveway. Letting the drone land in the backyard would avoid some of these problems, but not if there are trees.
Amazon has also warned customers that drone delivery is unavailable during periods of high demand for drone delivery.
UPS delivery drivers fought for and won a $170,000 salary. Ask them how degrading they feel their job is.
I am glad they are well paid, does that mean they aren’t doing a job that takes about a third grader level of education to perform? No. Does that mean it isn’t deadend? No.
Being well paid means exactly that and nothing more. EMT workers doing vital work but are often paid only a bit above minimum wage. Banksters are paid millions and produce nothing except taxpayer funded fraud.
