We don’t have either one. Someone is always flying these devices, they just aren’t onboard the aircraft. We also do not have any such thing as a self driving car. Someone is always driving, it’s just not you.
Driverless cars are here. Really.
I was in one yesterday (passenger).
Driver tapped “Autopilot” and took his hands off the wheel. Car did fine staying in lines on its own, even auto-braked when not clear whether another truck was going to stop at an intersection. Nobody was driving it, even remotely.
Owner hadn’t purchased the “full self driving” package ($$$) but it can be added, enabling the car to drive completely on its own (just set destination). There’s no “remote driver”.
