I don't believe in thousands of taxi drones

In order to make the city's urban transport faster and smoother in the future, a plan to build large fleets with taxi drones is in the making. 
I'm skeptical.
My pilot experience tells me that a storm is coming up. 
Hold on to your hats, good people.

Uber plans for a taxi vehicle with seating for four people. The first tests will start in 2020 in Dallas and Los Angeles. But Uber is not alone in having these high-flying plans. Both Chinese and German stakeholders are having the same thoughts.
In China, a start-up company named E-Hang has developed a self-driving drone, which they plan to start testing in Dubai this year.

The drone has space for one person and is equipped with an automatic navigation system for flights along various preprogrammed routes that the passenger can choose from. This drone vehicle has been tested in the outskirts of Canton in southern China.
- We will start mass production of our passenger drones early next year. The plan is to have an automated production line in place during 2018 in order to scale up the production, says E-hang CEO Hu Huazhi to Bloomberg.

But as I was saying; I am highly doubtful that this can actually work out. I do not have any scientific evidence, but based on what I learned during my education and my years as a traffic pilot, it tells me that this will not work if several thousands of vehicles are to share the airspace in and around a large city center.

Mainly, I'm thinking about how much air pressure it takes to lift one airplane. Having multiple vehicles in the air at the same time, the city will surely suffer from stiff breezes or even storms during rush hour. 

That being said, I repeat; hold on to your hats, good people!
