It's amazing what kind of fatalistic mentality we used to have, and how long it took to overcome it. And seeing the process it took to get here. I recall being told, don't recall when but it was probably in college, that it was a taxi cab driver, in the 60's or 70's, who started taking pictures of poorly designed road features. Like complete lack of guard rails, or bridge abutments that had no means to deflect cars from them, stuff like that--and presumably photos of the carnage that resulted.
It's easy to say, "don't drive into the ditch" or don't drive into a bridge column, or the like: but a few dollars worth of metal work can mean the difference between a fender bender and a death.
And of course, seatbelts are pretty cheap too, yet have pretty large return.
