So we have a policy from our leaders that they admit they cannot and will not enforce.I think it's a step in the right direction. It provides a target so that they can monitor and manage the risk of transmission on public transport. Government policy re coronavirus has been largely geared towards encouraging people to "do the right thing" and seek alternative means of travel where possible. They know it's not socially acceptable to (a) stop public transport completely, or (b) enforce these limits right now when this may leave people stranded at stations/stops/wharves for hours, making them late for work or school or going home. Until they can review the data and increase services where necessary (if at all possible) there isn't much else they can really do. If nothing else, the stickers that mark the "approved" seats on the bus are great for helping people to space out appropriately when it isn't over capacity.
Do we feel safer?
