I do not understand how these laws will kill the cycling culture.
I think it would be good if there was a law to wear a helmet. Will probably save lots of lives!

Helmet mechanics
One of the world's most prominent helmet test experts has stated that most helmets are physically incapable of sustaining impacts of the type associated with serious crashes; helmets provide protection only in low impact crashes under favourable circumstances [31]. Consumer tests of cycle helmets have shown that many helmets do not meet the standards to which they are accredited and only a very few helmets meet the higher standards most relevant to real-life crashes [32].
Adverse effects of helmets
Helmeted cyclists have been shown to be more likely to hit their heads if they crash and may be more likely to crash in the first place [34]. The disproportionate number of helmet wearers who believe that a helmet has saved their life (see above) is further evidence that helmet use might adversely affect crash involvement or outcome.
