If this is enforced the same way that it’s being enforced on public transport then it’ll be an utter shambles. Suddenly it seems, half the population has asthma. I’ve seen groups of teenagers regularly on without them, all clearly over the age of 11, although to be fair, some ‘adults’ are just as bad.
It is the right thing to do, but our public won’t conform. Police are far too busy on their knees to give out fines as well.
