Are you asking us to trust megacorps to not make maximum use of their surveillance data? When they've been caught time and again with the hand in the privacy cookie jar? When they turned the Internet into a 24/7 panopticon, with every web page carrying tens of surveillance beacons connected to the motherhive?

Compare to no route restrictions, where you would probably have the drones flying over people's back yards, which would be a considerable reduction in privacy.

No sane vendor will agree to these sort of terms and these companies do not care about privacy, they are all in the data mining and advertising business.

Unlike self-driving cars, self-flying drones do not have to worry about people running into their path, cars parked in the parking lane adjacent to their line suddenly opening a door into their line, or sharing the road with unpredictable human driven vehicles.

The drone route regulations will be starting with routes that have no other traffic except birds and insects. The routes can be designed so that there are different levels for north, south, east, and west travel, so except at the endpoints a drone never has to worry about encountering another drone moving in a different direction. It only has to deal with drones coming up from behind or coming up on drones ahead of it.
