> The fuel cost to haul 2.5 pounds 12 miles/day 100,000,000 times/day is not insignificant. That's a thousandth of the weight of a small 2500lb car, but much of the inefficiency is due to drag, so the impact is not even 1:1. In absolute terms, you can successfully argue that tons of CO2 are emitted as a result, but that's extremely marginal, at less than a tenth of a percent of emissions. I'm pretty sure you know how ridiculous your argument is, but if you were that much of a hippie, you'd know that shucking your clothes, ditching your spare tire, and driving on empty would be even better for the environment.
