“A tumbleweed against my car in Arizona when I woke up in the morning,” Tom Wolf wrote, diarylike about the photo he shot outside a Comfort Inn off Interstate 44. Wolf, WOW’s chief technology officer, had just bought this brand-new Lotus Elise (0 to 60 in four seconds) and broke it in by driving it from Los Angeles to Chicago and back over his recent vacation. But as with the Spanish inquisition, no one expects a tumbleweed. We have them inside our house, of course, but we call them dust bunnies.
