I too would like a citation. Plus calling a bike helmet's foam "flimsy" makes me question your argument. If you've ever removed the outer plastic (which is designed to crumble), you'd know that the foam is extremely tough. You could likely make the argument that over a certain speed your other body parts will sustain large enough injuries for the bike helmet to not matter, but that's not what you're arguing, you're arguing that the bike helmet itself stops working at an extremely low speed of 23 MpH or above. I actually Googled this a bit. Cannot find anything on it.

Ah, here's one from a pro-helmet resource: http://www.bhsi.org/limits.htm http://www.bhsi.org/limits.htm It indicates that helmets in the U.S. are only tested for 14 mph impacts. It's not that the helmet stops working altogether, it's that the helmet's protection really isn't sufficient. It'd be better to wear a full-face motorcycle helmet, but of course that'd be miserable on a bike.
