I'd assume the bars on Jeeps, 4Runners, FJ40s got put there mostly as a place to hold up the shoulder part of seat belts.Wow!
Waaayyyy back in 2008, my company did some testing on the roll cages on wranglers by lifting it upside down and dropping it from a certain height and measuring deflection. They failed miserably. It was more like a beauty bar than a roll cage. It was at that point that I was turned off from Jeep. I'm sure that my 4runner would not have held up much better that that 4door though!
