I think we need to distinguish between must-have and nice-to-have safety. To give an example, a car must not sponaneously disintegrate during normal high-way driving. That's what safety factor covers. If you floor it during heavy rain, and start skidding, crash into a tree, then that's kind of on you. Nevertheless the car will try to save you with abs breaks, crumple zones and airbags and what not. So the future you speak of is already kind of a reality with cars. But maybe expressing it as a pure factor is the wrong way to think about it.
