I didn't watch the video, but both practically and legally speaking, in the US when a car hits a pedestrian it's considered the car driver's fault, excepting some circumstances. The noise doesn't have anything to do with it- cars have to stop for pedestrians in marked crosswalks, and should stop at any formally defined crosswalk (not all "crosswalks" are directly labelled or signed as such).
