A linear scale for a graph like that is terribly misleading. The graph looks almost flat lately, but that&#x27;s just because it&#x27;s relatively near zero. Blow that section up to give it some vertical room and it will tell a different story.<p>Edit: just to put some actual numbers on this, Wikipedia says that deaths per 100 million vehicle miles in the US was 1.07 in 2014, and 1.44 in 2004. That&#x27;s an improvement of 25% in just the past ten years. You only have to go back 25 years to reach a fatality rate double that of 2014.
