Regulations don't avoid accidents. They cause corruption. I could just as easily present to you an example from Brasil: a couple of years back, when a track that was not ready to be used at Congonhas Airport in São Paulo was cleared for landing by ANAC(Agência Nacional de Aviação Civil or National Civil Aviation Agency) and that caused an accident that killed everyone on board. Your beloved regulation was the cause of the accident in this case.
So, there is no way to avoid every accident there is, but companies should be extremely afraid of engaging in practices that put their costumers' lives in danger without them knowing of that risk. If this occurs and it is proven, they should be heavily penalized for it. And that should be the deterring for "short cuts".
Unfortunately, people like you keep supporting ineffective measures such as regulations, which only generate corruption, unemployment, less development of new technologies, while doing nothing about actually preventing malpractices. The time and money wasted in regulating goods and services should be used in making the justice system more efficient in punishing those that engage in practices such as practices that endanger the lives of costumers while not making them aware of the risks of any given product or service.
