I don't think this is a useful comparison and I think it's a dishonest to present it this way.

You're trying to show that smartphones cause pedestrian deaths. This leaves out some very important info like figuring out if traffic accidents per mile driven have increased, if there are more pedestrians, the rates of death per accident and which kinds of vehicles are most associated with these deaths vs what people walk (or limp) away from.

From one of your sources, let's look at what that red line looks like in a different scale. You've stretched that way out. Looks like the overall trend for non pedestrian deaths is going down over the long run. So pedestrian deaths are increasing while non pedestrian deaths are decreasing. No wait, this graph shows a huge increase in non pedestrian deaths!
