I wouldn't say that each time they show people in ICU or the hospital may be brand new every time.
There is still a core of people that think it will never happen to them - they are the ones breaking all advice given, carrying on visiting friends and family for little reason, going miles by car to take their dogs or themselves for a walk, cycling way away from their own area, refusing to queue at supermarkets, and being rude to retail staff, I could go on and on !
Seeing people seriously ill in hospital really has the idea that it will hopefully give them a shock if it was to happen to them - but I very much doubt that it will make a difference.
The rest of us, to some extent also need to see just what is happening still, rather being lulled into a false sense of security when the numbers start to fall.
