The ONLY way things will change is either via a high profile crash (Tombstone Safety) or the real dirty secrets being given a wide as possible public audience.
Those things do not make change in themselves, they prompt change only when people care enough. They are not the ONLY mechanisms to make people care enough, they just happen to be the ones you are promoting. They can be very effective but can also, at times, be counterproductive. Behaviour modification is a complex topic, or so my dog tells me.
Anyway good luck
