Just like the Cusco ones right?
The cusco ones cant even pass any regulations, they are just for rigidity.

Dumb IMO. If I put in a cage, I want to not die with it in my car.

Not quite like cusco.. Cusco has eyelet style swivel connections troughout the cage. None of the tubes are connected by rigid joints. So you don't gain as much rigidity as you could have.
Cusco cages might make the car a little bit safer. Depends on if they hold out during a crash. All the forces of the crash have to pass through those single bolts (at least they are all in double shear).
From a purely physical standpoint, Cusco cages are about the worst that you can find. Lotsa bends in the main tubes, very narrow tubing and hinging connections. Maybe they work, maybe they don't, but they start out in life a little bit handicapped. I think its done to keep the cage cheap. No difficult fishmouth cutouts are needed and all the welding is limited to some weld on tabs.
