Not wishing to start an argument, but taking a few extra miles to go to the shops will not kill anyone. I have local shops I can walk to, but my Mam is over 70, and lives in a village with no shops. So either me or my sister go shopping for her, then need to drive over to her house to deliver. And I do take the longer back road route, rather than the shortest route. As far I as know, no one died in me taking the back road.
Yes, people will scream "What if you have an accident?". Well, I've never had one in over 20 years, so taking it easy in lighter than usual traffic, will not increase my chances.
Statistically, there is more chance you having an accident in your home, and anyone taking their car out for 20 minutes.
We all need to be sensible, but one mans sensible, is another mans hysteria. Social media is full of people in hysterics because someone they know went outside for a walk. People honestly think you are not allowed outside. We are. Just be sensible about it.
