Agree 100%. Musk has been promising autopilot for 5+ years, and only last year realized it is much tougher than the thought. To which I mumbled, "No shit, Sherlock."

My point: just driving a car, technology that has been around for 100+ years, by itself is not possible unless conditions are absolutely perfect, and even then it doesn't work 100%, but we're going to go live on another planet with different gravity, atmosphere, elements, etc? FFS that is a stupid idea at our level of technology, and maybe ever. Biology doesn't just "port" to another planet, Elon.
