The graph in the picture showed 16K deaths in 1923, for a US population of 111M then, with likely much smaller per capita driving miles than now. Now population is 323M, and there are around 5K pedestrian/car deaths annually [1]. We drive around 3 trillion miles annually[2].
If you can find the total or per capita miles driven in 1923, I think that would make the data complete. But it seems quite clear pedestrian deaths are vastly lower now than in 1923.
