Organizations like the National Highway Traffic Safety Administration (NHTSA) in the US track crash statistics, including fatalities and injuries. They can estimate the impact of safety improvements, but it's very difficult to say definitively how many people were *saved* because that would require knowing the counterfactual – how many people *would have* died without those improvements. It's a complex statistical challenge.
Therefore, you won't find a precise number representing "people saved." Instead, you'll find statistics on the reduction in fatalities and injuries, which can be interpreted as lives saved, but with inherent limitations in accuracy.
