GLANCE through a photo album of early automobiles and you’ll find an eclectic assortment of vehicles, including three-wheeled machines and bicycle-like contraptions. You’d be hard-pressed to identify many as cars.
Early consumers were confused, too, until innovators finally converged on a carriage-like design and coined the term “horseless carriage” in the 1890s, giving a clear point of comparison. More than 100 years later, we can learn from their example.
