In fact, here's a news story related to whether it's OK to drive short distances to meet one person to exercise. https://www.bbc.co.uk/news/uk-englan...shire-55560814

The police force involved, Derbyshire Police, said driving for exercise was "not in the spirit" of lockdown.
I find that quite alarming, and disagree with them on that.

*As always, I don't know the full details of the case, and the press always misrepresent news by design or incompetence.
