Per that link, pedestrian fatalities had a sudden break in trend and skyrocketed right when motorcyclist deaths stopped climbing and flattened. Wouldn't you expect the hypothesis of new vehicles increasing ped deaths show up in motorcycle fatalities too? It seems much more plausible from this baseline data that the introduction of the smartphone is more relevant: the skyrocketing happened at the precise time the smartphone took off, and smartphone ubiquity naturally wouldn't affect motorcyclist fatality (while new vehicle shapes would). Of course, there are myriad other potential explanations, including the trend towards urbanization and walkable cities over the last decade and a half, but I don't see how you can conclude that the pedestrian fatality graph is useful evidence of the greater dangers of newer vehicle designs.
