If there was a mobility service that's cheaper than owning a car, more reliable, and you get to sit in the back seat instead of being stressed out in the front seat, why would you own a car?

If Uber is lower-priced, then more people will want it. And if more people want it and can afford it, then you have more cars on the road. And if you have more cars on the road, then your pickup times are lower, your reliability is better. The lower-cost product ends up being more luxurious than the high-end one.

When you start to automate, you start to do the self-driving thing, you make it much more efficient. When these cars go into self-driving, you start to become a robotics company.

We want transportation as reliable as running water.

I spent a disproportionate amount of my time in a car in L.A. I'm 35 years old. If you add up the hours spent in cars, it would be years.

Uber is efficiency with elegance on top. That's why I buy an iPhone instead of an average cell phone, why I go to a nice restaurant and pay a little bit more. It's for the experience.
