You had the option when you bought a car, and still you went for the less safe option. If most people act like you, you can imagine why an airline that has safety measures that people are not willing to pay for, will go out of business. Therefore, the option is not there because there is no market for it. If you think there is a market, please go ahead and start your own airline and see how well you do with policies like "no plane will ever depart without working T/R", and how many more people will choose your airline because of this.

Any company that does not operate to the principle to weigh benefits against cost will go out of business eventually. "Professional negligence"? I suggest you stick to your dream world.
