Redpoint5, I respectfully disagree. Safety can be engineered in from he beginning with little or no decrease in performance. Say I build a kayak with positive flotation built in to the bow and stern. The kayak flips over and the person can easily right the boat, climb back in and bail out the water. Where is the performance lost? Maybe a few cubic feet of storage? I'm sure as your boat is sinking you would have been glad to give that up. You are confusing issues here, Capitalism, performance and safety, Capitalism says make the product so we can get great return for our investors. Make the product just safe enough to pass some regulations and so too many people won't die. Performance I have found is to be largely ego driven and would not have to be a compromise with safety if our expectations matched our supposed wisdom. Do we really need a motorcycle capable of 200 mph delivered to an 18 year old who just got their drivers license? You get your performance sure, but how hard would it be to have a factory rev-limiter that clocks miles and shuts off after 5000 miles of "training time". Might cost $5 worth of a chip or two. Well that's not American I here you cry. Don't tell me how to drive my bike! Ego. No, performance at least regarding motor vehicles, is mostly ego. And your argument about a zero miles per hour car is absurd. It would be unusable and therefore irrelevant. Safety, lastly is the most elusive. There is your own personal safety but how fair is it to take other people out with you because of your need to please Wall Street or because your bike or car is faster than your brain? Life isn't 100% safe for sure, but we seem to make the same mistakes over and over again because we make assumptions like "Safety and performance are always a compromise" which gives us the permission to cut corners when we know better.
The whole problem with the Boeing Max 8 could have been avoided by simply limiting the up travel of the stabilizer or elevator to avoid a stall. But greed, not performance gets in the way and says the plane must get to flight level 350 as quick as possible so our planes looks as good as Airbus's. Performance, I guess I'm saying, is a state of mind that is easily adjusted or modified by careful reasoning of what do you REALLY need here to accomplish the job. Is ten miles more range on paper for an EV worth a battery fire? Safety or lack of it is lights out, game over.
Except in a few rare instances, safety and performance do not belong in the same equation. It is only us stupid humans who are taught that to provide ego rushes or more money.
