Australia

You can tell how much a state cares about cyclists by whether they already allow this. It's illegal in NSW and Victoria. It's legal in Queensland, WA, and SA. It should be no surprise that NSW and Vic were also the last states to implement minimum passing laws, in 2018 and 2021, respectively.

NSW and Vic are crap states.

I saw several older people around town take up cycling once the law was changed to allow adults to cycle on footpaths. They change between surface based on their capabilities and perceived safety as everyone should. Look out for yourself first and worry about obeying laws designed to kill people second. Cycling on paths has its merits for all ages though it can still be dangerous due to driveways etc. The commonwealth should force universal adoption to bring the backward high road fatality states up to standard. Until then mass civil disobedience is the way.

When I was couriering, riding on the footpath was legal.

No one believed it. I had made cards of the 2 relevant road rules for handing out purposes but usually it was just an argument.

There needs to be cycling roads that are just for cycling, not just painted green strips on existing roads. Big ask but it's what we need for the majority of persons to use bikes as an actual mode of transportation.
