"In order to keep the love going, you want to keep it fun." — Travis Kalanick

If somebody can offer value at a cheaper price, they should. But that also means Uber should, too.

Competition is good.

My politics are: I'm a trustbuster. Very focused. And yeah, I'm pro-efficiency. I want the most economic activity at the lowest price possible. It's good for everybody; it's not red or blue.

We have this culture valued at Uber, which we call the champions' mind-set. And champions' mind-set isn't always about winning. It's about putting everything you have on the field, every ounce of passion and energy you have. And if you get knocked down, overcoming adversity.
