Lots of sensible suggestions have been made on here.
I agree with a lot of what has been said here. There is a lot that has been suggested that could help us all. The recent events have shown us the value of community and food security. However I have particularly noticed the clearer air, even in a place where the air is normally considered clear. I think we all would really appreciate safer cycling and walking, particularly on the smaller roads and lanes. Now the traffic has come back, I no longer feel safe. I used to cycle about many years ago, before the numbers of visitors in cars thing really took off, but stopped after too many scary moments. I think with the increase in cycle touring as well as the clean air and health benefits, if more could be done to help make it safer when not in a car, that could benefit us all. Also secure cycle parking at shopping areas and places like beaches could help promote cycle travel.
