You don’t wear your seat belt for yourself… you wear it for the ones you love. My 2007 Prius saved my life. Everything in it worked exactly as designed.
The shoulder belt left a big bruise on across my chest.
The Air bag deployed in literally the blink of an eye and kept me from going thru the windshield.
Everything that was suppose to crumple, crumpled and not a single window in the car was broken.
Needless to say, I got another Prius.
