When you factor in population growth, it's clear that the mobility model that we have today simply will not work tomorrow. Four billion clean cars on the road are still four billion cars, and a traffic jam with no emissions is still a traffic jam.

One of the things I've had the advantage of, growing up and being close to the top management of this company and other companies for most of my life, is seeing how CEOs start to believe in their own infallibility. And that really scares me.

I don't ever want to believe my own press clippings, good or bad.

As long as gas is cheaper than bottled water, we can't be in a position of dictating to the consumer what to buy.

It's amazing how much data is out there. The question is how do we put it in a form that's usable?

Nobody's irreplaceable, including me. I think for too long we've had a cult of personality in this company and in this industry, and frankly, I'd like to see that diminish.

I believe very strongly that corporations could and should be a major force for resolving social and environmental concerns in the twenty-first century.
