But of course we don't know the full story do we. As a trained police driver one buttumes that he knew how to drive safely at such speeds. I am sure that a suitably trained and experienced driver could do so, and the question in my mind is not what numberical speed he was doing, but whether he was endangering other road users. We don't know the answer to that one. For example, on an empty road with nobody else for several miles, it might be acceptably safe.
Speed is not dangerous per se, it is inappropriate speed for the conditions that is dangerous. I would venture to suggest that at such a speed on a public road, that would have to mean no real or potential hazards in sight. That way, he could probably still stop in the distance he could see to be clear. But that being said, it seems unlikely that 84 in a 30 could ever be acceptably safe, unless the limit really was very poorly set.
But I deplore the fact that a different law seems to have been applied in this case. If I drove at such a speed I would probably be locked up, whether or not I had the skills to do so safely.
