Detroit spent millions trying to understand what buyers wanted—and acted accordingly. It wasn’t a case of “Grosse Pointe myopians” dictating their preferences. Almost every failure—from the Henry J to the Edsel to the longer-wider-faster American Motors mid-60s models—was an example of product planners misreading market forces. Every notable success, from the early Rambler to the ponycar to the musclecar, was an example of getting it right. For whatever they built (and they built some pretty bad cars): Don’t blame Detroit. Blame us.
