Not sure why you are so concerned with acceleration.... If you're on a bike, it doesnt matter if you get hit by a truck at 30, 45, or 60. You're most likely dead anyways, adnd if you survive, there is a good chance you wish you were dead.
at 40 mph there is a 90 percent chance they will be killed.
at 35 mph there is a 50 percent chance they will be killed.
at 30 mph there is a 20 percent chance they will be killed.
at 20 mph there is a 2.5 percent chance they will be killed.
thanks, that is very interesting data, i wonder how they collected it. i supposed if you are on a bike wearing a helmet these percentages all go down....
