Twenty-three fatal crashes with seat belts occurring in Colorado during 1962 and the first eight months of 1963 are studied in detail and the following conclusions are reached:​

1. The design and construction of current automobiles are inherently dangerous and will cause deaths and serious injuries in spite of seat belts or even more adequate personnel restraints.
2. The seat belt is not enough, upper torso control is required, and the carmakers must be led to provide built-in attachment points for these additional straps.
3. Cars must be built so that the steering shaft is not driven backward into the driver, when the front end is deformed in a crash.
4. Car doors must have stronger latches, the "improved" ones are not good enough.
5. Frames and bodies must be stronger to prevent penetration by the striking car in side impacts.
6. Bumpers must be reasonably designed to become a protective device for cars and their occupants. Current bumpers are a scandal and a disgrace.
