If he had been carrying a passenger then that person would almost certainly have been dead. However if he had been carrying a passenger and had a 6 point roll cage with door bars that person may have lived. Like I said i all depends on the type of crash.
Now let's take the "if's" out of that scenario and look at what actually happened. The guy didn't have a passenger and didn't have a cage fitted either, but he he did actually walk away from the collison unharmed! Now by the same hypothetical "if's"..... "if" he had have had a cage fitted, then the car may not have crumpled as much and therfore would not have absorbed the forces from the impact anywhere near as much either. The forces would therefore have been far more likely to have been transferred through him and his vital organs instead, never mind his hypothetical passenger, he himself may well have been killed! (and as I seem to recall, I think that I did make comments to that effect on that original thread 
)
Yes the effectiveness of a cage does depend upon the type of collision, but in the majority of road collisions a cage will increase your risk of injury as opposed to reducing it. This is why they are not fitted as a safety device to road cars as standard, they are designed specifically for the specific risks associated in competitive Motorsport not the road. Statistical evidence shows that the presence of a cage in a road car increases the risk of injury to the occupants, which is why fitting one to a road car will generally increase your insurance premium.
I really wish you would stop spouting this old rubbish!
Or at least post up the 'official statistics' as evidence and not just some random posts from forums from people who have no real idea.
Why must you try and 'scaremonger' people when they innocently post up regarding roll cages?
I think by now the most acceptable message is "yes fit one if you want BUT please ensure for maximum safety they are used inconjunction with properly fitted safety harnesses and bucket seats"
Trying to worry people by saying that you will die is just a tad 'over the top' and as for all this old baloney about internal injuries and the like is not doing the safety harness and bucket seat manufacturers much good is it.
I can tell you FROM PERSONAL EXPERIENCE that if it wasn't for my rollcage, harness and decent seat
I WOULD BE DEAD!!!
As for crumple zones, PAH!
Crumple zones on modern cars are designed and placed OUTSIDE of the safety cage area, ie around the engine bay and boot areas.
So the bodywork at either end will crumple and the safety cage (technically a rollcage) will protect the passengers in its 'ring of steel' The chances of internal injuries are GREATER due to the occupants moving around inside the car due to only having standard seatbelts.
So in relation, a Mini has its crumple zones at the front and rear (same as modern cars) in the sense of the bonnet, front panel, wings and boot area will crumple in the event of an accident. The roll cage will do the job of stopping whatevers hit your car from trying to get into the interior area ie like a modern cars safety cage.
Yes you may pick up some injuries from the restraints, BUT you'll be alive!
Better alive than dead.
Oh and insurance companies will hike up the price for ANY modifications, small or large. It goes up on a roll cage generally because of the facture of
a) Its quite a large, obvious modification.
b) It gives you a false sense of 'too much security' so you may be inclined to drive faster/worse.
c) It may have not have been fitted properly, or with the rest of the safety gear, or be upto any decent standard.
Its NOT about internal injuries.
So folks I would ignore this drivel about rollcages are gonna get you.
Fit one if you want.
BUT:-
Fit a good one.
Fit it or get it fitted properly.
Fit\get fitted a good pair of Harnesses.
Fit\get fitted good quality bucket or similiar seats.
Fit\get fitted some padding.
Remember to get advise from your insurance company first, some are ok with it, some can be a bit funny. But if its all done properly and above board then you probably won't have much of a problem.
