The saved highway tool converts sixty miles per hour using one point four six six six seven feet per second per mile per hour. That is about eighty-eight feet per second. During its one point five second reaction interval, the modeled car travels about one hundred thirty-two feet before braking. Increasing reaction time to the source control maximum of two point five seconds raises this distance to about two hundred twenty feet. The bars compare the actual one point five and two point five second input settings using the exact source conversion. Braking distance in this saved model is speed squared divided by twice deceleration. Deceleration is friction coefficient times thirty-two point two. With coefficient point four, it is twelve point eight eight feet per second squared. At sixty miles per hour, braking takes about three hundred point six feet. At thirty it takes one quarter as much, about seventy-five point two feet. Reaction distance must be added separately; the total at sixty is about four hundred thirty-two point six feet. The default obstacle is two hundred fifty feet away. Reaction consumes about one hundred thirty-two, leaving about one hundred eighteen feet for braking. The remaining speed squared is initial speed squared minus twice deceleration times that remaining distance. It remains positive, so the model predicts an impact around forty-six point eight miles per hour. The exported brake-deceleration input is retained, but the actual calculation uses friction times gravity; the video explains that implementation, not a calibrated road-safety guarantee.
