The world isn't going to rush out and buy self-driving cars just because the people who want to sell self-driving cars tell us how awesome they'll be. It just doesn't work that way.
Thirty years ago, you could just as easily have written the following:
"The world isn't going to rush out and buy cellular phones just because the people who want to sell cellular phones tell us how awesome they'll be. It just doesn't work that way."
Back then, Ma Bell ran the U.S. telecom industry. Nearly every home had a landline, with regulated rates. Public phones were everywhere. What possible motivation could people have to buy a $400 smartphone every two years, and pay $50 or $100 a month in connection fees on top of that? Yet here we are today.
Self-driving cars aren't going to overturn transportation because they're "awesome", but because they'll be so damned useful to so many people, not the least of which will be the large segment of the population that wants the convenience of personal transportation, but cannot drive.
Add to that the estimated 250 billion USD cost each year in the U.S. alone due to auto accidents, along with 35,000 deaths and millions of injuries (some permanently disabling), and there is in fact an enormous financial (and humanitarian) incentive to get self-driving cars on the road ASAP.
Twenty years from now we'll be looking back and wondering how we ever managed without autonomous transportation, just as we now wonder how we managed before the cell / smartphone era. People can kick and scream about the future all they want, but it's coming nonetheless.
