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.
Truck driver? You know the most common job in the US. Do the people who you are advocating for know you have so little respect for their intelligence that you think they literally can do nothing else except drive a van around? I would be pretty insulted if someone was saying that my limitations were my current job.
You need a different license to drive a big rig truck than you do a package delivery truck. They would have to be retrained. Amazon sure won’t pay for that. Who will?
And do you think trucking wouldn’t also get automated?
