I don't doubt the conclusions of the report, really, but it's missing the part where it explains how helmet laws suppressed cycling. You didn't ride your bike to school because you had to wear a helmet? Maybe. Or maybe you didn't ride your bike to school because nobody rides their bike to school anymore because their parents are scared to let them. (That also changed in the last 25 years or so).
Obviously both are a factor and maybe mine is the lesser, I'm just saying that it's not in the report.
I'd be far more inclined to jump on my bike and ride to my local shops instead of driving if I didn't have to wear a helmet. If I'm riding on the shoulder of a busy road then I wear a helmet by choice, but riding around my quiet neighbourhood is a far more pleasant experience without a helmet.
Riding around city streets in Europe without a helmet further demonstrated to me just how nanny-state Australia really is.
