IKR. A woman I knew was brushed by a car and fell. She wasn't going fast at all. She wasn't injured by the impact of the car but rather by her head colliding with the blacktop. (Broke her jaw, too, but a helmet would not have prevented that.) Suffered a serious closed head injury that required her being put in a medically-induced coma. I went to see her in the hospital post-coma. I almost puked when I saw her condition.
