The solution to transport problems in the growing city would be a new quadcopter taxi. It will safely transport passengers in secure capsules equipped with safety parachutes. A person in the cabin won't need to know or do anything. Autonomous system will guarantee take-off after selection and confirmation of the route, identify obstacles on the way and fly around them, and then safely land at the destination point. All quadcopters will operate from a single electronic centre and will be based on neural networks, which is why protecting against cyber attacks is an important part of their design.
