A couple of points about "modern" helmets
Original cycle helmets (as opposed to "hair nets") were a fairly thick chunk of polystyrene with the ability to absorb energy.
As design has progressed, fashion and ventilation have become a greater priority in design,at the cost of effectiveness
When you put a vent in the helmet it removes the absorptive material and reduces the amount of energy that can be absorbed. Additionally the material that is left has to be denser and stiffer to support the helmet design.
Modern helmets really compromise the basics of helmet design.
Then you get to a stage where the little material that is left is unable to (even in the denser form) support the design and a stiff uncompressible carbon fibre or other sort of material is introduced to support the design shape.
.. and all that is before you get to the other design faults such as "snag points"
Isn't it rather ironic that we have such a vociferous pro-helmet who are advocating an inferior product and not questioning the decrease in effectiveness
Could this be the reason so many modern helmets "crack" - there simply isn't enough stiff material to support the structure in and impact and the frail bars snap
Note how these random examples from a Google search have all failed at a frail cross piece in the design
all in all, it's a manufacturers dream product. buy one break it buy another break it buy another break it buy another break it (or BOBIBABIBABIBA)
