Well nothings new. I had seen the total lack of interest in Lord Campbel's bicycle's and figured that was partly because in order to ride them one has to be in a posession of a helmet. Now ladies with handbags may dig around inside and locate one and even a spare for a friend but as for the rest of us .....
I figured what was needed was a flat pack helmet that could be dispensed from a vending machine. My guess is you could sell a cardboard and coolite helmet for about $2-$3.
So I had a look on the net and of course it has been done before.

It seems that the traditional makers feel a bit miffed becuase there were posts aplenty poo pooing it on the grounds of structural integrity and crash worthyness. Something I had not considered when sitting around thinking of how this could be done. It seems that the problem is as much a political and spin problem as it is an engineering one. I guess the price just went up to $5 per helmet and a big BCC grant to get the inevitable "Independant test" that would be required by "a current affair"
I doubt if the hat in this photo would pass any sort of standard test except perhaps for oragami.

Mind you one does wonder whether if it were made of carbon fiber and the holes were much much smaller......
As at start of 2011 helmets must meet AS2063:2008

Apparantly a US standard Snell B95 is similar. Given that SAI Global make a profit from selling standards, it may be easier to actually find a copy of the Snell B95 document.
So far I have not been able to find a copy of either standard nor what would be even more interesting would be a description of the actual testing.
I note however that recently the Lord Mayor has embarked upon a cunning alternative plan to save his bicycles. Get elected to state parliment and repeal the stupid helment law and free up those bicycles from almost mandatory detention.
