Gas prices have fallen as we approach the end of summer. Who could've imagined that?

If you'll pardon my sarcasm, you might find fascination in Traffic: Why We Drive the Way We Do (And What It Says About Us), by Tom Vanderbilt, which gets top billing in today's NYT Book Review:

Vanderbilt cites a statistic that nearly 80 percent of crashes involve drivers not paying attention for up to three seconds.

It was pretty funny a few weeks ago when a caller to the John DePetro Show lambasted political officials and questioned why NASA hasn't come up with a more fuel-efficient car engine.

This bright light was apparently unaware that the major car manufacturers could have years ago offered more fuel-efficient cars.

The Apeiron Institute's Sustainable Living Festival is this weekend, and I've got a related Q+A with Apeiron's Brad Hyson in this week's Phoenix:

In the current environment — in which people are pissed off about the price of gas, the economy is bad, and people are reconsidering some of their habits — does it make it easier to promote a message of sustainability?
