In terms of automotive history, we often think of Tesla in the present but not in the past. Yet in 1920, the Pierce-Arrow, a very high-end automobile manufacturer, featured a patented, Waltham-built "air-friction" speedometer, invented by engineering genius Nikola Tesla. The speedometer had a jeweled mechanism that operated by the friction of the air generated within within the instrument by the speed of the car. Unlike the ordinary cable-operated speedometer, it was free of any inaccuracies caused by dirt, grease, or wear of gears.
This blog will expand on themes and topics first mentioned in my book, "The Automobile and American Life." I hope to comment on recent developments in the automobile industry, reviews of my readings on the history of the automobile, drafts of my new work, contributions from friends, descriptions of the museums and car shows I attend and anything else relevant.
