My wife and I recently finished an introductory auto mechanics class — which was an incredibly fun time and an excellent experience — and one of the recurring themes of the class was just how miserable, unreliable, and dangerous cars were ~50 years ago.  This video is a good example of that; it&#x27;s not just mileage or seat belts or airbags, it&#x27;s everything from tires to engines to brakes.
