I'd say, not so much the fault of the roll bar manufacturer, but more so the wrong type for that type of racing/car. That's more of an autocross, low speed roll over protection.
In our SCCA road racing, we can't race with a roll cage like that, even with a 100 hp car. That hoop failed because it doesn't even have a diagonal bar.
I had to watch the whole video just to be able to tell what kind of car it was (Camaro).
The associated drone video is scary. The motorcycle in the other lane could've been involved with a little more bad luck,.
