I was thinking about that when I was dropping my 6 year old off at some hobbies earlier - it’s pretty much expected to have learned how to ride a bicycle before starting school, and it massively expands the area you can go to by yourself. When she went to school by bicycle she can easily make a detour via a shop to spend some pocket money before coming home, while by foot that’d be rather time consuming.
Quite a lot of friends from outside of Europe either can’t ride a bicycle, or were learning it as adult after moving here, though.
edit: the high number of replies mentioning “swimming” made me realize that I had that filed as a basic skill pretty much everybody has - probably due to swimming lessons being a mandatory part of school education here.
How to walk on ice is a big one. How to cross a street is another one here in Chicago (hint: look at the cars, not the lights).
For the ice one you mean taking a running start, sliding on it, and yelling weeeeeeeee… Right?
Just like crossing a street.
In Chicago it’s the same thing.
I didn’t, but that’s another learned skill in this category, yes.
