Lets assume the environment does meet half way. How resilient would such a system be. How easily can it be attacked to fiddle with the ability of the car to navigate safely? Also, and much longer term, isnt it kind of weird to think that human infrastructure can only be seen to massively scale i. The planet so long as we turn the planet into a cyborg? Isnt it weird and wasteful to build a planet wide cage of tech infrastructure for the evonomies of the world to survive and for human civilization to operate along the trajectory we are currently pointing? Seems dismal to me.
