Why are police giving advice, anyway? Bicycling without a helmet is not an offence; operating a vehicle without sufficient care is.
Edit: I say this because plenty of people erroneously think cyclists are required to wear helmets. That is reinforced when police are quoted in articles suggesting it in the same way as they suggest that people pay attention while driving.
