Car talk.

• Position: Letters - Letter to the Editor

Stephanie Mencimer's otherwise excellent review of Keith Bradsher's new book High and Mighty: SUVs ("Bumper Mentality," December) was unfortunately marred by the false assertion that most SUV customers are affluent, and often socially liberal, baby boomers. In fact, automakers know--and their marketing efforts reflect--that the biggest consumers of the biggest SUVs (Lincoln Navigator, Ford Excursion, Cadillac Escalade, etc.) are affluent conservatives.

Good luck trying to maneuver an SUV down the maze of side roads in any Japanese city.

LARRY WIEBE Tokyo, Japan Three cheers from up north, where SUVs aren't quite as popular--save for Alberta, our most Americanized and insecure province. I (carefully) drove my non-ego-inflating Ford Tempo in that province for several years, always checking around me for the arrogant--and usually incompetent--drivers who massaged their tiny self-esteem in these portable kill vehicles. Perhaps Canada suffers as a nation from a bit of the "soccer-mom" complex, but this, after all, is not such a bad thing. My compliments (and thanks) for placing this story into the public discourse where it belongs.
