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.
I think you’re missing the cars part of flying cars.
Like, the dream isn’t to drive your car to the airport and get into an airplane. The “car” part of flying cars is about having one in your driveway.
You can get a used Cessna for under $60k:

But, the issue isn’t the up-front cost. Because a plane isn’t a flying car, you have to store it somewhere, and that isn’t cheap. Even just tying it down outdoors can be more than $150/month. Then there are the operating costs, which are much higher than cars: insurance, annual inspections, fuel, maintenance, etc.
The Webster dictionary defines a car as a vehicle that moves on wheels which airplanes definitely are.
You can have your airplane in your driveway (or more commonly your grage). They are called fly-in communities and are more common than you think.
If you’re having to resort to the dictionary definition, you know you’re flailing.
The idea behind a flying car is that everyone could have one in their driveway (not the rare people who live in fly-in communities) and that they can use a combination of driving and flying to get places. That’s what all the flying-car companies are working towards, that’s what people dream of having. Having to live right next to an airport, or having to drive their car to the airport to get their plane isn’t the “flying car” dream.
