Why would he put his ID under the seat & leave it there??
Maybe it fell out of his pocket?
Have you ever dropped your ID in a car and then took several minutes to hunt for it because it fell in some cranny? I’m thinking that’s what happened to this guy’s ID. And he didn’t have time to look for it, and maybe did not realize it had fallen from his pocket. Especially if it fell out while the driver was still fighting for his life.
“Why would he put his ID under the seat & leave it there??”
Maybe he expexted to be killed and wanted the world to know who he was??
