Driving the workforce right along all legal and industry lobbied limits all the timit doesn't equate to safety either, comparable to driving a sports car all the time along the rev limiter. Yes, it will work, for some time.
Unfortunately now and then reality bites and some companies that think safety is too expensive will get to try an accident.
I always felt the best and final prevention for such unwelcome experiences are competent, confident, sharp pilots at the pointy end who have the ability to say 'no' if circumstances require. Companies may lack fantasy what they're setting themselves up for if they're not allowing those qualities to build.
