I don't think there is anybody who could deny that driving in excess of 70 on a motorway is dangerous
I see. Could you clarify a point for me please? Is it dangerous because that is the speed you are driving at or dangerous because you are exceeding the limit?
This is a critical difference. It is, in very general terms, dangerous to drive at high speed, even if you are the only user of the road. This is because you are less able to slow down or stop or steer away when hazards occur, in terms of reaction time and distance travelled while actually shedding speed. In this case, driving in excess of 70 on a motorway is dangerous because 70 is a high speed.
Additionally, when other road users are sharing the road, another aspect is introduced. Specifically, lane sharing depends on synchronised acquisition and release of lane resources. Synchronisation is made much more difficult by mixed traffic at largely disparate speeds. This aspect is related (via the politics of driving) to the law, inasmuch as the driving community has settled on the 70 limit, which in turn creates standard lane speed expectations for synchronised acquisition and release of lane resources. It is far from perfect, like a data bus, but it seems to serve that purpose. A similar condition exists for town driving, where the focus is more on the synchronised acquisition and release of other road resources, such as lanes at junctions, roundabouts and traffic lights and so on. Again, synchronisation would be more difficult by mixed traffic at dissimilar speeds, and no realistic user-expectation could be set. This means that a compromise is in the offing, and much of the material on this site is uncompromising, including some of my own, hence the friction.
For example, the roads are not for fun, but for getting about on quickly and safely, but I sense that some posters here are sports car drivers put out by restrictions. To bad for them, but serious drivers don’t want speed kids attached to their bumpers!
