Fred J. Schaafsma, a top engineer for General Motors, says, "Sport-utility owners tend to be more like 'I wonder how people view me,' and are more willing to trade off flexibility or functionality to get that." According to Bradsher, internal industry market research concluded that S.U.V.s tend to be bought by people who are insecure, vain, self-centered, and self-absorbed, who are frequently nervous about their marriages, and who lack confidence in their driving skills. Ford's S.U.V. designers took their cues from seeing "fashionably dressed women wearing hiking boots or even work boots while walking through expensive malls." Toyota's top marketing executive in the United States, Bradsher writes, loves to tell the story of how at a focus group in Los Angeles "an elegant woman in the group said that she needed her full-sized Lexus LX 470 to drive up over the curb and onto lawns to park at large parties in Beverly Hills." One of Ford's senior marketing executives was even blunter: "The only time those S.U.V.s are going to be off-road is when they miss the driveway at 3 a.m."
