To address your last paragraph, everyone going 85-90 is less safe than everyone going 70-75, you are correct. However, you individually going 70-75 when everyone else is going 85-90 is less safe than you going 85-90 like everyone else in the exact same situation. >there are always people willing to go faster and faster That’s why no one says “go as fast as the fastest vehicle you see”, it is “go with the general speed of traffic”. That’s an exercise for human judgement to figure that one out, which is why imo it isn’t a smart idea to have the car automatically lock you out of overriding the speed limit.
