How safe is your roll bar?

[Cobra Lite]

For those of you who don't check Jalopnik daily...
Here is a warning for all of us who like to drive "briskly"
No fear, neither the driver nor his passenger were injured, amazingly!

Notice the bolt-in rollbar punched through the floor with the bolt plate and bolts showing. (see photo 8 full size)
Notice the roof and rollbar together did little to protect the people.
Now, how do you get out of the inverted car? Doors won't open.
Add a little leaking fuel and hot engine parts....
Not a good way to go.
I think they crawled out through the trunk after the car was turned back over.

Bolt in roll bars are "Style Bars" if they are bolted to the floor pan. Even the rear bracing will do nothing if the vertical bars give.

Now, how would your car do in a similar situation. Or more important, how would your head do? The very tiny footprint of a single hoop bar impacting dirt with the weight of the car on it will sink in to some degree. The Mustang had already lost all its speed before flopping on the roof as you can see it didn't slide.

Wear a helmet. Pad your rollbar. Drive carefully.

Enjoy life, it is priceless!
