They have made many improvements on autos & safety.
Even if sensible gun laws were enacted, like no civilian needs an ak-47 or mega clips of ammo, people will still shoot people with guns. However, many would be spared.
We make laws to help prevent death, but no law is perfect.
So to say unless you can prevent all shootings, its not worth making betters laws, is disingenuous.
a snippet from page xii
The index stayed essentially unchanged from 1955 (100) to 1960 (99.6), but it had dropped to 44
by 2012. In other words, this report estimates that the fatality risk in the average car or LTV on
the road in 2012 would be 56 percent lower than in the average vehicle on the road in 1960, even
given the same exposure, drivers, roadways, and medicine. The reduction includes the effects of
crash avoidance technologies such as ESC, occupant protection technologies such as seat belts
and air bags, and programs to increase belt use.
The report estimates that vehicle safety technologies
saved 613,501 lives from 1960 through 2012, including 27,621 in 2012.
