I've seen that too somewhere. Try youtubing Eos roll bars and see what comes up...or you could search this site for youtube as lots of other posts have included videos/demos of the Eos before.I don't want to find out. I did see somewhere on YouTube a video of how they work. I just don't want to personally experience this!
Apologies if this has been posted before, but there are some good (?) pictures and videos of the EOS undergoing its Euro NCAP testing. Its here if you have the stomach.
I've seen pictures of the Focus CC with the roll-over bars up. They punch up through the rear window. I'm sure the EOS is the same.
My old CC was involved in a front-end crash that was enough to write it off. It looked a mess but I walked away with a slight whack in the chest off the selt belt, some air bag burns on my hands and an achy shoulder. They build these cars to protect.
It looked to me like the roll bars did not deploy until the car started twisting after the front impact. Makes sense as the roll bars arnt required in a front impact but the movement after probably feels like a roll motion - especially given the forces involved. I guess it has to be sensitive enough to deploy them at the first sign of a roll so they are up locked and ready before the car is on its roof.Note the time taken for the roll-over bars to activate in the frontal impact test - I hope the deployment is a lot quicker in a roll-over accident.
I think a bit of glass would be the least of your problems when your bouffant is rubbing the road.I just watched that and nearly threw up! Especially as that is the colour of my car! Seems like it protects reasonably well. I was always concerned by the glass roof shattering but this didn't seem possible in these tests and that kind of reassured me although it obviously wasn't a massive worry as I bought one regardless of the glass roof! lol
