Fines are pointless. You would need at least four policemen in every single bus or wagon and that’s impossible. All that remains is to either avoid public transport or use ear plugs combined with ANC headphones.
There will never be such a world and there never was. Laws and their execution was always arbitrary. What worked for you killed a lot of people. Classic survivorship bias.
The campain is stupid because it will have either no or the opposite effect. Of course! Because we’re dealing with reckless assholes at best or psychopaths at worst. Human garbage. How stupid must someone be to believe that putting posters everywhere with “Please be nice” would make human garbage behave any better?
“The 60-Year-Old-Virgin” wouldn’t work as a comedy. But it could be interesting as a realistic drama. Of course with a real downer ending like the protagonist commiting suicide in the end. I would watch it.
