I think we all agree that the most important factor here to getting people on bikes is providing the feeling of safety (+ actual safety) and convenience, which I would argue needs to be better infrastructure first, helmet law relaxations second.
Can you imagine if they do helmet law relaxations first? The media would have a field day.
If someone is more discouraged to ride because helmets are a hassle or might ruin their hair, instead of death by car due to poor infrastructure and car-centrism, then I'd look at such a person sideways.
