Pedestrians are at a serious disadvantage when it comes to collisions. If a vehicle hits them, they have no real protection against the impact. Their bodies take the entire force of the blow, which can result in fatal injuries.
Imagine being in a state where your likelihood of being in a crash is higher than in others. For example, as a pedestrian in Florida, you have the highest risk of being involved in a pedestrian accident than anyone in any other state.
