I'm pleased that the police over reach is being discussed.
For example, I am pregnant and I have a toddler who regularly falls over as he's learning to walk. If I go for a walk in my town, as I did yesterday, I encounter 35+ people, the majority of whom it is impossible to keep 2 m distance from on pavements and paths. My toddler has to stay in his buggy.
If I drive 10 mins (which, incidentally is not as far as I have to drive to go to the supermarket), to go to my normal walking location, there are acres and acres of open space and I do not have to get in close proximity to anyone. There is one gate, which I wear gloves to open. There is no livestock so my dog can be off the lead chasing a ball. My toddler is free to exercise as there is no broken glass, dog owners are diligent about picking up dog waste.
Common sense tells me the latter option is safer and better for our health. Exercise for everyone is important. I'm not going to pass on/receive the virus there, and no, contrary to the belief of many on here, I am very unlikely to break my leg on the gentle grassed gradient of a walk I've been doing pretty much every day for the past year and a half. I am not worried about having to call mountain rescue for assistance. Yet according to many on mumsnet I am being utterly selfish for driving and walking there every day.
