It used to be illegal to use wireless internet gear in Australia unless it had AS clearance. That made wireless internet stuff here quite expensive, until people just ignored the law and started importing gear in large numbers. Eventually the govt gave up. Much the same thing has happened with telephones (both fixed and mobile), etc.
I see helmets (both motorcycle and pushbike) as much the same thing - the AS compliance thing is mainly about protectionism. If enough people ignore/flout the law, then the law will change to reflect reality.
And I reckon if the authorities got wind of it they'd use it to make a motza out of it (fines of course!!

) You'd be getting pulled over every 5 minutes for a helmet check!

It used to be standard practice for a while down here a number of years ago. Bikes were a bit of a target for a while and anything and everything was checked "Ad Nauseum".

Used to have to factor in the time spent with the Plods into your travelling time! All for our own good of course!!
