It's funny, because prior to the creation of the Department of Transportation, Automakers did not really talk about safety of their products. Fatalities were often blamed on bad drivers, not car designs that prioritized aesthetic over human safety.

To quote President Johnson: “In this age of space, we are getting plenty of information about how to send men into space and how to bring them home. Yet we don’t know for certain whether more auto collisions are caused by faulty brakes, or by soft shoulders, or by drunk drivers, or even by the deer crossing a highway.” He signed the Traffic Safety Act which created crash databases. This now includes the Fatality Analysis Reporting System which easily allows for anyone looking at these accidents to gather years of data across the country. Due to a prioritization of safety, the odds of dying in a car crash have dropped by 80% since the 1960s.

Of course, with guns, Congress has passed laws making it Illegal for the ATF to create a searchable database of their records, and illegal to create a registry of gun owners as they have with cars.
