General Motors has a new promotion going where if you buy a Hummer, Tahoo, or Yukon, a gas truck follows you around wherever you go.
Well, not really--they offer you gas at $1.99 per gallon for a year. Estimated savings: $2,270. No mention of externalized costs: mid-east wars, heated atmospheres, resource depletion. But I guess we already know who will be paying for those.
