Your proposal for what to make the shell of helmets from is

not a particularly hard material, despite your assertion.

Indeed not, as anyone who has used polycarbonate spectacle lenses will
know. It resists penetrative impact well, but penetrative impact is
hardly considered a major issue in bicycle helmet design.

Polycarbonate lenses Saved My Sight (TM). And yes, actually, that one
is pretty much provable.


Yep - and wanking for England destroyed it again.
