Why are there so many pedestrian involved accident manga/anime?
You're much more likely to get killed in an accident involving two or more vehicles.
one can only assume that the regular viewer (as identified by the producers of animu) in japan usually dont have a car since they are weeeaboos.
So a pedestrian vs. car scene makes more sense than a soccermom crahing into a truck on the freeway.
even more interessting: notice that most animes where the MC or at least an important Char drives a vehicle, the show is on the bell curve on the "good" side? (mecha != vehicles..)
