Krugman on Reducing Travel Energy

He makes a very good point, that getting people to buy cars that get better gas mileage is the easy part of this.

The hard part is getting people to drive less too, since we have engaged in policies that have subsidized choices that require driving over the past 50 + years.

As for me, I'm about 5¼ Miles from the terminus of the Baltimore Subway, so I'll do OK, I can bicycle to it.
