These rules are convoluted and near impossible to apply. Specific braking speeds for some objects compared to others? That requires reliable computer vision, which hasn't been demonstrated anywhere yet.
And those speeds? 92mph is 148kph! Why the fuck are cars even permitted to be capable of that when no road in the country allows it? And why would you want to introduce unpredictable braking scenarios at such speeds?
What is feasible is a speed limiter based on the posted limit, but that'd be too practical.
