Self-driving cars will enable car-sharing even in spread-out suburbs. A car will come to you just when you need it. And when you are done with it, the car will just drive away, so you won't even have to look for parking.

I have a strong disrespect for authority and for rules. Including gravity. Gravity sucks.

I've developed my passion for cars that drive themselves from being stuck in traffic for many, many, many hours of my life. I don't know what it adds up to, but I feel like I've lost a year or two just in traffic. That's big to me. That's a lot of time, a lot of money that I just lose on the road.

Question every assumption and go towards the problem, like the way they flew to the moon. We should have more moon shots and flights to the moon in areas of societal importance.

Every time I act on a fear, I feel disappointed in myself. I have a lot of fear. If I can quit all fear in my life and all guilt, then I tend to be much, much more living up to my standards. I've never seen a person fail if they didn't fear failure.

The Jetsons had them in the 1960s. They were the defining element of 'Knight Rider' in the 1980s: cars that drive themselves. Self-driving cars appear in countless science fiction movies. By Hollywood standards, they are so normal we don't even notice them. But in real life, they still don't exist. What if you could buy one today?
