What for me is the big question, is how much "social distancing" will become a permanent feature of our society long after it is no longer a legal obligation, with a corresponding permanent effect on our way of life and the business models of some industries.
Right now the window between the most cautious it is possible to be and what is actually illegal is very narrow, but this will widen over time.
I know lots of people that are taking measures(sometimes of questionable value) which go beyond the mandatory social distancing, like immediately washing all their clothes on high heat after returning home.
In a few months the lockdown will be gone, but the virus will still be out there and just as deadly.
Even after the measures are over, how long, if ever, will it be that people would be willing to share a compartment with a stranger on a heritage railway, visit a nightclub, or eat cake brought in by a co-worker(even though there was always a risk of catching cold or flu from things like this). After all, even a vaccine has been developed, you have no way of knowing who has had it.
