I guess you guys crying about safety and a roll bar in the passenger compartment have never ridden in a Jeep?!
To be fair though, the cages in Jeeps and Broncos and other similar offroad vehicles are much further away from your head than a rollbar in a passenger car, and are also padded in the critical spots.
That being said, I've had a rollbar in a fox mustang before though and I never really worried about it. It's just a risk I'm willing to accept. I may eventually put a 6pt bar in my Fury but for now I haul enough people around in it that I don't want them to have to climb around the bars to get to the backseat.
