Fully agreed. I t-boned a car that cut me off, doing approximately 60-80 km/h. My shoulder dented the car's roof through the door frame. I went flying through the air and landed on my back, on cement-cast stones protruding slightly from the cement (the decorative edge of the roundabout).

I walked out of the hospital a couple of days later. I wouldn't have been walking then, nor today, if it wasn't for the protective shoulder pads and spine protection in my jacket. It took about 18 months of physiotherapy to stand and walk normally again, but still.

Edit: I realise this is a POV with n=1, but it convinced me.
