Could we also remove the requirement of rollbars for convertibles? Basically the same thing.
Agree with this. When I went wrong side up with no cage & OEM 3-point, the vehicle structure (A pillars & B pillars) held up well (2010 Mustang), but it was tight. There was some intrusion in the centre roof & windshield areas. I needed the flexibility to move within the car. If the rollover had of been more severe (ie multiple roll or hard impact roll), there would likely have been even more intrusion into the occupant space that needed to be avoided.

To be held upright in place by a 5-point and HANS definitely requires a cage to support the roof in a rollover IMHO.
