What would $20 gas look like?

The Freakonomics blog interviews author Christopher Steiner about his book $20 Per Gallon:

[At $8 per gallon, predicted in 2019,] our restaurant world won't be terribly different from what we’re used to now. We'll always have Chinese food — or at least the Americanized version of it (batter it, fry it, smother it in sweet and tangy sauce). The tricky part of the question concerns foods like sushi. When gas is $8 per gallon, sushi will still be hanging around. Things get interesting, however, at $18 per gallon.

By the time gas has reached $18 [predicted in 2029-2039], most people will live in places where density dictates that schools be grouped closer together, putting them within an easy walk or a brief bike ride.

Q: What are some things you suggest people enjoy now before they’re gone?

A: Eat sushi. Drive the trans-Canadian highway (in summer). Go to Australia. Go see Tokyo and take notes — life will be more like that and less like, say, Omaha, in the future.

I wish I had time to read this book. Maybe if I get all my Duke reading done before next week. As if.
