Most automobiles spend about 80 percent of their time sitting around doing nothing. They're gasoline powered; they go to very high speeds, which in fact, under urban conditions, you don't need. These high speeds generate enormous safety requirements and so on and so forth. Now you can incrementally tweak the automobile. You can make the power train more efficient and you can enhance safety and all of these sorts of things that are very worthwhile.

...people have always known, at least since Moses denounced the Golden Calf, that images were dangerous, that they can captivate the onlooker and steal the soul.

We are surrounded by pictures; we have an abundance of theories about them, but it doesn't seem to do us any good. Knowing what pictures are doing, understanding them, doesn't seem necessarily to give us power over them.

An interlude of false innocence has passed. Today, as we enter the post-photographic era, we must face once again the ineradicable fragility of our ontological distinctions between the imaginary and the real, and the tragic elusiveness of the Cartesian dream. We have indeed learnt to fix the shadows, but not to secure their meanings or to stabilize their truth values; they still flicker on the walls of Plato's cave.

That's not a utopian vision. It is a set of ideas that we think are important to discuss. Those ideas largely have to do with sustainability of cities. The ability of cities to, over time, remain in balance with the resource streams that are available to them, and they have to do with social justice and equity of the fundamental conditions of satisfactory citizenship.

Automobile is one of the most successful inventions of all time, but in my view, it is thoroughly obsolete already. And so by fundamentally rethinking the automobile, thinking of it as a robot on four wheels, essentially, something that can communicate with other intelligent devices, it can operate in a coordinated way, you can really start to fundamentally rethink urban personal mobility.
