Everyone is a pedestrian. It is a facet of life that we don't often think about, but when you consider the incredible risk that pedestrians take on every time they walk on the sidewalk and cross the street, it becomes a crucial facet. Pedestrians have no safety equipment; they have no padding; they have no seat belts; they just have themselves. And when they are hit by a motor vehicle, they often suffer terrible or even fatal injuries.
There are also many people who are bicyclists. Again, this is an activity that we may take for granted, but being a bicyclist is dangerous as well. Much like pedestrians, they have almost no padding or protection to help them when a vehicle strikes them. And much like pedestrians, they can suffer terrible or fatal injuries when they are involved in a motor vehicle accident.
