As this video proves, most of the time, when they use this particular trope in film, they do it in a very unintelligent and unrealistic way.
For example, the victim stands in the middle of the road talking to a person on the sidewalk for quite a few seconds before a bus which has perfectly good visibility ahead of it hits the victim at a speed well above the speed limit for that road.
In any case, the video contains other automobiles too and rumours abound that it's the same driver in every scene.
There's more where that came from.
