Have to be careful with those stats.

To the best of my knowledge (and some other wannabee advocates) 90-91 was
not year mandatory helmet laws were "introduced" but the time mandatory
helmet laws became heavily "enforced".

It did coincide with the release of the super nintendo also i believe =)

Was talking to the ex pres of Bike Sydney and he seemed to recall that "the
wear a helmet" media campaign did use scare tactics by showing cyclists
getting hit by motor vehicles.
