Earlier quoted context omitted.
You only talk about fatalities but people can get hit by cars without dying and be still in urgent need of an ambulance (often so they don't die later).
It's not going to change the conclusion unless you believe that death is a very rare outcome of being struck by a car. Think about it. Do you personally know of any occasion on which a child was run over? In what sense could it be a "common problem"?
I have myself witnessed a child being hit by a car and a few years back one died in my city. Both in school zones where cars sped through illegally. I'm in Germany with only 1/4 of the US car fatality rate per person.
