At 1st I wasn't gonna chime in negatively. But now you are just sounding foolish! Any Roll cage that the welds snap off wasn't welded professionally or anywhere near correctly! Go & youtube some of the wrecks in NHRA(Bruce Allen & Kenny Koretsky come to mind 1st) & see the integrity of roll cage construction. Many more lives are save because of roll bars/ cages. As for your device, I wouldn't trust Heim joints bolted in on such a severe angle to maintain integrity if it were my life depending on it. The intrusiveness of the back seat area alone would make me say no to it. This appears more & more like what people are saying- a gimmicky product. Has it been sufficiently crash tested? Any reputable associations certify or endorse it? That picture of the failed bar has to get you wondering. That's a pretty extreme failure! Maybe from an extreme impact too. But how much failure is necessary to cause injury or death? Maybe a serious impact only causes 1/2 the damage to the bar, but that may be too much to endure for the occupants involved.
