Back up cameras are becoming an accident hazard. Folks rely on them too much out of habit and are backing right out in front of on coming traffic from the sides. So you are actually better off turning your head and looking anyway.
I was walking in the supermarket parking lot a couple days ago and that’s exactly what happened to me. As I’m just about to walk behind a car, its backup lights went on. I immediately froze. The driver was watching his camera and never ONCE looked around even though I was not far from his driver’s door. And I could plainly see him. He backed all the way out and drove off — never once did he swivel his head! I was SO tempted to thump his sheet metal and scream in fake pain.
So, be ultra aware of these idiots in parking lots.
