Q: If we transitioned to flying cars in the distant future then how the heck would we control traffic for people's safety? Fly drones to serve as lane markers and hold up signs? That would be a several metric shit-tons of drones. And I wonder how you'd prevent all the cars from just trying to fly over top of traffic jams and endanger each other? Now you've got a third dimension of regulation to worry about that you didn't have before, far dwarfing the implementation details of today's air traffic control systems since there are so many more cars. It's such a common futuristic idea but it seems really difficult to realistically manage, even if we had the tech for it. What do you think?
A: could have like digital lanes. the cars are not capable of going outside the lanes. Or, they could possibly allow you to go a little bit out of lane, enough that it is still safe, but they can still fine people for it. could be a good revenue stream, to help pay for all the digital lanes
