No buyers for Hummers plus no buyers for homes in far flung suburbs equals The End.  NPR’s Marketplace recently reported that “drive-until-you-qualify” suburbs are facing a rash of foreclosures because high gas prices make them undesirable; even a decent mortgage rate can’t compete against $3-a-gallon gas.  Ghost Town Suburbia, a made-for-TV movie in the making.

Which is why I was surprised to read that driving is on the rise again. In 2007, as the economic crisis began, driving declined for the first time in decades. According to USA Today, a study by traffic-watchers INRIX “found that driving increased by 0.3% in September, 0.2% in October, 0.3% in November and 0.2% in December over the same periods a year earlier, according to federal data.”

Increased driving is partly the result of an as-yet unfulfilled promise to put public transit back on the front burner; many of those outer suburbs would be more feasable digs if trains or busses or rapid transit reached them. But it’s also a sign that the economy is slowly on the mend. Retail sales are higher, and fewer people are filing for unemployment (although the latter may have more to do with Congressional delay on the unemployment benefits extension).

Sadly, the best thing for reducing traffic congestion, in the absence of a comprehensive public transit system, is a sour economy. Rick Schuman of INRIX told USA Today, “As the job situation goes, so goes congestion. If we have a recovery and we start seeing employment starting to grow, congestion will grow along with it.”

Here’s the question:  if the existing,  largely empty suburban greenfield developments (products of wayward policies though they may be) will inevitably fill back up as the economy eases, wouldn’t it be better for mass transit to trundle their denizens back and forth to work?  Of course it would.  It’s time to front-burner public transit to the foreclosing far-out lands, a better way to  tackle congestion and the housing crisis at once.

And now is the time; cars are on the comeback. While Toyota and GM are both suffering from recalls, it turns out that the Hummer brand might have a buyer after all.
