This country has always been governed by consent. Draconian enforcement of the lockdown could well have led to even more breaches by peoople who have a dislike of being told what to do. Call in civil disobedience/ voting with their feet whatever.
As TOBW said, considering it has more or less been by consent it has held up remarkably well. Even the traffic flow has only recently increased, and a lot of that may mean people using their cars to shop/go to work instead of risking public transport, there by maintaining social distance.
I believe a lot of the traffic increase may be people going to work as living on a main road I note that in the evenings/night the traffic is virtually zero which indicates people aren't just going for a swan (Except eric
).
