One of the most unfortunate syndromes with which we have to deal is the "let's see what we can get away with" idea.
One starting point is youth and cars with which they kill themselves and others by trying to get away with excessive speeds, drunken or drug-affected driving, illegal street drags and so on. Underlying all this is the "it can't happen to me; I'm bulletproof" clause, which is proven wrong so often that you have to wonder whether they have liquid fabric softener for brains.
Some of those who survive to reach middle age now believe the "bullet proof" theory - they did get away with it. Why is there crime? Why is there this disregard for rules? Because they reckon it's good to beat the cops.
I'd be rich if I had ten bucks for everyone I have heard saying the this pandemic is all bulldust and young people don't catch it anyway so why should they care?
Short of a jackhammer or angle grinder, I don't see how we get it into their thick skulls that it's fair dinkum and bloody serious.
