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?

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.

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.

In 50 years, there will be only 10 institutions in the world delivering higher education and Udacity has a shot at being one of them.

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.

I have a really deep belief that we create technologies to empower ourselves. We've invented a lot of technology that just makes us all faster and better, and I'm generally a big fan of this. I just want to make sure that this technology stays subservient to people. People are the number one entity there is on this planet.
