The tech maybe heading towards a perfect World of automation but where not in that boat yet and the problem of rouge states and hackers are yet to resolved, if ever they can be.
Only this morning I read about Russia testing a Star Wars type weapon in space last week so there goes your GPS tracking up the Swanny and God knows what else the North Koreans, Russians, China etc. are up to right now never mind in the future.
This is a big problem that has not hit the fan yet but forget fully automated cars for the next decade though one day it will become safe for sure but not in the 20’s or 30’s that I can see.
