I didn't know that the involuntary startled reflex that we have (in theory, as protection) which kicks in if we're rear-ended actually can make the potential for injuries even worse. So, it's better that the reflex is triggered before the crash like via a sound or tightening the seat belts.
I wonder if the pre-collision system warnings in some cars are actually intended to do just that. I've seen some demo videos of the Prius w/the advanced technology package (which has PCS) and a message that says "BRAKE!" will show up, accompanied by beeping. I believe the seat belts will tighten up too.
There was an test near the end where they increased a driver's cognitive load. I'd have trouble completing that task if I were driving.
The experimental windshield system that GM was working on was interesting. It would be really cool to have something like what they were showing.
