Pedestrians don't teleport in front of your car. It takes them time to cover the distance from the sidewalk to the middle of your lane. At the normal walking speed (3 mph) it takes 2.73 seconds to cover the width of a lane (12 feet). No matter how "out of the shadows" someone comes, no way that distance is less than 6 feet, that's 1.36 seconds. Situations where the distance a pedestrian has to cover to go from invisible to in front of your car are numerous, like people crossing the street in front of a stopped bus. But that's when you slow down, and instead of 38 mph, you do 5 mph.

Look, you can quote science, and studies, or you can talk to anyone who has a driver license. In case you yourself have one, then all I'm saying here should not be news to you, or unreasonable.
