When implementing policy you need to deal with politics. These decisions are not made in a computer on data alone, every bill will hear numerous testimonies and requires the judgment of lawmakers.

What you're proposing is counter-intuitive to most people's everyday experience, ie. wearing protection is safer than not wearing it. Sorry, but if you really want to convince people you are going to need more than data, because the other side will have their own stats - and crying mothers and all that jazz.
