One struggles to think of a worse vehicle at a worse time. Introduced shortly after 9/11 — an event whose causes were tangled in America's unquenchable thirst for oil — the Hummer H2 sent all the wrong signals. It was/is arrogantly huge, overtly militaristic, openly scornful of the common good. As a vehicle choice, the H2 was a spiteful reactionary riposte to notions that, you know, maybe we all shouldn't be driving tanks that get 10 miles per gallon. Not surprisingly, the green-niks struck back. A Hummer dealership was torched in Southern California. The H2 was also a PR catastrophe for GM, who happened to be repossessing and crushing the few EV1 electric cars at the time. It all contributed to GM's emerging image as the Dick Cheney of car companies.
