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'm really looking forward to a time when generations after us look back and say how ridiculous it was that humans were driving cars.

I learned to basically pull my own weight, just do my own thing. I spent a lot of time alone and I loved it. It was actually really great because to the present day I love spending time alone. I go bicycling alone, go climbing alone and I just love being with myself and observing myself and learning something.

That's what Google taught me. Aim higher. Udacity is my playground - to radically experiment and find out. I've seen the light.

We humans usually feel that we are the best at everything we do, that we can safely drive ourselves. But tens of thousands of people die every year. We need to be open to having technology assist us, to find ways in which technology makes us safer.

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?

People mainly fail because they fear failure.
