I basically don't think that the way we do things is that dependent on one resource, such as oil. There can be different kinds of engines for cars. I think that solar heating, wind heating can substitute for a lot of uses for oil. I'd like to see those things happen because they are more sustainable in any case. But I do not think that running out of oil is not going to bother us that much. I think we have got to be rescued by something or we really are going down a slippery slope.

The entrepreneurial investors of the time just want to repeat themselves indefinitely and don't know when to stop. You can't do that. And so finally the housing boom, or the auto boom, or whatever it is that's been carrying things along, runs out of customers.

I think that intelligent people to a great extent are captives of their time or place.

You can't rely on bringing people downtown, you have to put them there.

All through organized history, if you wanted prosperity you had to have cities. Cities are places that attract new people with new ideas.

Traffic congestion is caused by vehicles, not by people in themselves.

The second mode to deal with unsafe cities is to take refuge in vehicles. This is the technique practiced in the big wild-animal reservations of Africa, where tourists are warned to leave their cars under no circumstances until they reach a lodge. It is also the technique practiced in Los Angeles.
