Tesla, GM, Audi, BMW, Ford, Volvo and more, all have self-driving features in cars today. Which ones have this "inherent" feature to limit where you can drive? None of them. If the government passes a law that cars have to ask permission, it will be on all cars, it's nothing to do with self-driving.

That has nothing to do with self-driving cars. A new gas powered, manually driven car today could have a GPS device that logs where you drive, uploads it and demands permission to travel, the engine would just cut out if it decided that was not allowed. Look into what happens to financed cars now if you stop making payments, they know exactly where the car is, and they can remotely disable it. Your concern about your freedoms being eroded has nothing to do with self-driving cars.

The Lantern Project is a mobile fingerprint scanner already in use in the UK: NPIA I've seen it being used in the field on a reality TV show called "Police Interceptors" (yes, edited clips to make the Police look good)....the one time it confirmed a driver was who they said they were when they had no id on them. The other time the copper said, "no, you are actually Frank Smith, date of birth xxx", the suspect confirmed this and was arrested for outstanding warrants.

I hope they have a few air strips along the way that are long enough for the flyer to land successfully - you know, in case of emergency.

I'm sure landing would not be a problem. A large amount of the weight at take off would be fuel. After jettisoning any fuel this plane could land on a regular size runway anywhere in the world.
