David Haywood provides concrete evidence on RNZ on why cycle helmet laws do more harm than good.
http://podcast.radionz.co.nz/ntn/ntn-20 ... od-048.mp3
Main arguments.
1.Cycling is less risky than motorcycling
2.Helmet laws lead to less cyclists.
3.Less cyclists make it more dangerous for the remaining cyclists as drivers are less aware of cyclists.
4.Overall health of populaton is affected due to less cycling.
5.Drivers pass more closely to cyclists who have helmets than those who do not wear helmets.
