Once in a while I'll ponder just what inspires people who will never drive off-road to buy SUVs. Yesterday I hit upon the perfect analogy when I saw a watch commercial on TV. Some watchmaker was selling a watch that runs off solar power. Just a few minutes of light on its face stores enough energy for it to operate for several days. I thought, "That's kind of cool. If I had any need for a watch ever, I'd get that one." And then the thought popped into my mind, "But what if I go to Antarctica...for the winter." With no light for several months on end, that thing would be dead. This same type of logic, applied when car shopping, is the reason so many people who don't need SUVs buy them.
