We're blaming drivers because it's a core responsibility of driving to not injure or kill people with your vehicle.

There's no corresponding responsibility inherent in walking. In fact many people who walk also have other statuses or impairments that prevent them from fully perceiving the world they are walking through, such as blindness or being a child.

It is the driver's obligation to ensure the safety of the people around which they choose to operate their vehicle, regardless of their awareness or behavior.
