The last 20 years of American history can be summarized by car size getting smaller after 9/11 due to rising gas prices. Then the domestication of the hummer because gas guzzling became a symbol of defiance against the A-rabs. Then the giant SUVs also getting steadily smaller due to even higher gas prices. Then finally settling on re-hummerization of cars by convincing people they need a giant pickup truck to haul a 2x4 from the hardware store for their weekend projects.
