“As to people looking right at something and running into it anyway, I would imagine that is something similar to what WWII fighter pilots succumbed to at times; target fixation.”
We had a classic–and tragic–example of that a few days ago in my county. A man from Maine was driving a pickup truck and towing a trailer full of cattle that he had just bought in my area. He detected a problem with the trailer, and pulled onto the shoulder of the interstate in order to fix the problem.
Shortly after he had pulled onto the shoulder, a young man in a Hyundai hit the trailer. That young man exited his car in order to, apparently, exchange information with the truck driver. While they were standing on the shoulder, an Econoline-type van did a direct hit on the back of the trailer, killing the young man. Additionally, two passengers in the van died, along with several of the cattle.
The “move over” law is essentially designed to protect police and first responders who are parked on the shoulder, but–if possible–I try to move out of the right lane if there is a disabled vehicle of any kind on the shoulder. Unfortunately, some people have a different concept of “move over”, and they move over to the shoulder of the road where they hit vehicles and people.
Here is an account of that accident:
