Most states in the United States drivers are required to yield to pedestrians crossing in crosswalks. Most drivers don't understand what yield means

So sad that some walkers are so stupid. They have as much responsibility to be safe and avoid accidents as drivers do. At night, they wear dark clothing, nothing reflective, and do not carry a light. Of course, some of them are drunk or on drugs. In Florida, if they survive, they can be ticketed just like a driver. Not much of a penalty if they don't have a license to suspend or revoke, or a car to impound.
Even worse are the jaywalkers who cross in the middle of the block.
