Nup. Not how bicycle protective helmets have ever been designed to work.softy wrote:I do believe all those holes must weaken the structure.
They are not designed to protect from crushing of your skull by a two-tonne vehicle. Even my old MSR would not have done that. They are simply impact energy attenuators ie. they absorb the impact of a fall onto a hard surface. The strength of the helmet structure does not matter, as long as it basically stays in one piece.
