Any sufficiently advanced technology is indistinguishable from magic
I think this is one reason that some people can't comprehend the reality of a self-driving vehicle and thus are imagining a far more distant timeframe.
Yet, despite that, we have virtually every car company, who is intimately working with the technology, saying it'll be a reality sometime within the next 5 years --
Ford (L4 - 2021) Ford Targets Fully Autonomous Vehicle for Ride Sharing in 2021; Invests in New Tech Companies, Doubles Silicon Valley Team | Ford Media Center
GM ("sooner than you may expect") GM’s first fully autonomous car will be electric and launch on Lyft
Volvo (L4 - 2020) Volvo's first self-driving car has a big edge over the competition — and it's coming sooner than you think
BMW (L4 - 2021) BMW’s Bold Plan to Make a Fully Self-Driving Car by 2021
Audi (L3 - 2018) Audi kicks the race for self-driving cars into a higher gear
Tesla (L3 - 2017+, L4 - ???) "
A hell of a lot sooner than most people think. It blows my (Elon's) mind."
That was just a 5-minute search.
To not believe these dates is to believe that everyone in the industry, who are both testing and developing the technology, is either lying or wrong, solely based on our ability to comprehend the technology from the outside looking in. How long regulators take is another question, but the way things generally work is that someplace will allow these cars first (like
Michigan), and then as the safety records become more and more apparent others will follow, state-by-state, and then federal and country standards catch up. And, then it's everywhere.
