That's what I don't understand. How it could fold like that.
You don't see the point though - the roll cage protected the cockpit as a whole with what we could say were "minor" mis-shapes compared to what the same cockpit without a cage would have been like (i dread to think
) . The reason the pariticular section of the roll cage bends so "easily" is the force acting (from one of the concrete bollards hitting the roof) over the small cross-sectional area of the tube (its only a hollow cylinder of metal) - Yes the material is very strong, but theres no way it could withstand the immense force of the car (travelling at god knows how many MPH) hitting the concrete over an area as small as 10cm^2.
