By far the majority of Cobra accidents are spinouts after losing traction in the rear. Rollovers are comparatively rare, but they do happen. In the case of the more common spinout, the car often impacts an immovable object from the rear. In quite a few reported cases the passengers survived ( single roll bar)while the driver died or was severely injured from blunt force trauma to the back of the head. If your head can touch or even stretch to reach the roll bar when you're seated in the car, just think what will happen to you or your passenger's head if you get rear ended, or even on the rebound in a frontal impact. Roll bars are intended for use in racing applications where the driver's noggin is protected by a helmet. Roll bars on street driven Cobras are more a function of SC-style than actual safety.
Just drive with a bit of extra care when you have a passenger. Accept your own risks - including smacking your head on a steel bar - when you're by yourself. Motorcycles and Cobras are more about enjoyment than foolproof safety. Enjoy accordingly.
