The quantitative limits on distances travelled for exercise are a way of trying to make rules as simple as possible to follow, and to stop thousands of people from Liverpool and Manchester from descending on the Lake District and Snowdonia honey pots at the same time, which is what will happen if the rule was just "you can go outside for exercise" with no further specific limitation and we have a spectacular Spring like last year (in fact it did happen last year on the south coast beaches). It is also desirable to have quantitative restrictions so they can be objectively, rather than subjectively enforced, which makes the job easier for the police who are assigned the job of enforcement. Even then, sometimes they get it badly wrong (Derbyshire).
The message is usually delivered in the soundbite "stay at home", which contradicts what we are actually permitted to do. Even "stay at home as much as possible" contradicts what we are encouraged to do, which is to get out regularly for exercise in order to keep fit and healthy (both mentally and physically). If I were to stay at home as much as possible, I wouldn't be going out for exercise, because it is
possible not to.
You say the message is easy to understand - well yes, it is; but when people are out for a walk or doing their shopping in the supermarket, they're not at home, so in those circumstances it's irrelevant. What
is relevant in all situations is keeping a sufficient distance from others (at least 2m), which seems to be largely ignored in the supermarkets I've been to.
That message doesn't seem to be getting through. So it seems to me that the 2m rule, which is just as easy to understand as "stay at home", would be better as the central message for people to grasp, since it applies wherever you are. The issue of thousands of people from Liverpool and Manchester descending on the Lake District etc. was already covered under tier 2 regulations (which is not to say people from tier 4 areas were not illegally visiting the Lake District when it was in tier 2). Again, if we always keep in mind the distancing principle, then we'll avoid crowded spots and seek out quieter ones, if the rules and/or the police allow us to.
