IMHO "Don't piss off the whole world, just piss off one country" is a bad
solution, if there is no need to piss off anyone at all.

Yes, but I would like us to define what the different national defaults are,
so that everyone can work off the same playbook.

For example, in Noppia, bikes can do the wrong one down one way streets. One
way streets are just tagged oneway, nothing special.
In Stevia, they can't.

We define use cases:
UC1) Oneway street with bikes allowed in wrong direction
UC2) Oneway street with bikes not allowed in wrong direction

We have a 2x2 matrix:

               UC1
UC2
----------------------------------------------------------------
Noppia: oneway=true                  | oneway=true;bicycle=oneway
Stevia: oneway=true;bicycle=twoway   | oneway=true

That's the table that needs to go in the wiki so that everyone understands
how to code the same thing in different countries.

Meanwhile the area for Noppia could be tagged
"bicycle_rule:wrong_way_in_oneway_permitted" or whatever.
