When I was in New York, I was making a living. We had a summer house and a car that I could put in a garage. That's something for a stage actor.

Your car should drive itself. It's amazing to me that we let humans drive cars... It's a bug that cars were invented before computers.

Consider the perverse effect cap and trade has on altruistic actions. Say you decide to buy a small, high-efficiency car. That reduces your emissions, but not your country's. Instead it allows somebody else to buy a bigger S.U.V. - because the total emissions are set by the cap.

Every summer my husband and I pack our suitcases, load our kids into the car, and drive from tense, crowded New York City to my family's cottage in Maine. It's on an island, with stretches of sea and sandy beaches, rocky coasts, and pine trees. We barbecue, swim, lie around, and try to do nothing.

It's like, no matter what I do, I always feel like I'm five years old, and I end up in the back of my father's car looking out the window, and nothing has changed in 25 years.
