I think it's interesting that you have a somewhat valid point for a few use cases, but are quite myopic to the different users.

If I add in:

- I have children

- Temperatures range from -15C to +5C to -15C on the same day, and same outing

=> I need to pack backup clothing for the children in case they get wet in the +5 weather, and backup snow winter clothing for when it's -15 and they get wet.

=> We aren't talking niceties, a 25kg child exposed to sub zero weather in wet clothing will approach hypothermia and other detrimental conditions quickly.

If I add in:

- physical limitation including breathing (reliant on oxygen), exercise intolerance, amputation, pregnancy, pregnancy induced physical limitations, broken limbs, nerve damage, inner ear disorders due to concussion or older age

=> "So are your legs. Walk and bike." becomes... well, I hope you see.
