More Prii at which location: Whole Foods on a weekend or an arboretum on Earth Day weekend?

A recent experience at the Morton Arboretum led me to this question regarding where I was more likely to see Toyota Prii:

-The parking lot for Whole Foods on a weekend

-At the arboretum on Earth Day weekend

Since certain lifestyle and consumption choices are tied to other lifestyle patterns (for example: TV shows), connecting Prius owners to these two places may not be that surprising. One study had this to say about small car owners:

Small Car: Prius, Honda Civic, Smart Car
According to a study by researchers at UC Davis, “What type of vehicle do people drive?
The role of attitude and lifestyle in influencing vehicle type choice,” small car drivers are more pro-environmental and prefer higher density neighborhoods than drivers of others types of cars. This isn’t surprising; if you live in a big city, it’s simply easier to park with a small car and if you’re concerned about the environment, you’ll want something that’s more fuel-efficient. Small car drivers, unlike other categories of drivers, don’t necessarily see their cars as a ticket to freedom. They aren’t workaholics or status seekers who try to display wealth. They want to lessen their impact on the earth and have a reliable car—and find a parking spot.

When considering the number of Prii at the arboretum, there were also a large number of vans and SUVs, vehicles less friendly toward the environment. Can a driver claim to be an environmentalist while also driving a large vehicle? Is a Prius a special badge of honor?

Fuel efficiency = bankrupt highways?

Brian hit the issue almost a year ago, but Jordan Weissmann at the Atlantic recently re-focused attention on the problem of funding U.S. highways with fuel taxes:

Since back in the Eisenhower era, the federal government has maintained a Highway Trust Fund, paid for mostly by taxes on fuel, that helps cover the repair and construction of our country’s roads, bridges, and mass transit. The idea was that drivers themselves should bear some of the cost the roads they used. Unfortunately, Congress hasn’t raised the gas tax since 1993. Since then, inflation has eaten away at least a third of its value…[and] two new challenges [have] emerged. First, Americans started caring about the fuel efficiency again, as skyrocketing oil prices ended the era of gas-guzzling SUVs. Then the recession struck, and penny-pinching drivers logged fewer miles to save on gas.

The upshot, of course, is that

less money is flowing into the Highway Trust Fund, which is now facing potential insolvency in 2013, according to the Congressional Budget Office.

I guess it’s good that fuel efficiency gains are having an impact?  (Ah, unintended consequences.)  Looks like we’re headed into a world where cars will have to start paying by the mile–or the highways are going to get a lot worse.
