Again, this is not relations as categories in any way. People suggesting 
that really didn't think enough about it.

It's combining roads that are connected to *each other*, with a special 
property, and the non-category like feature here is that they form one 
*entity*: a zone if you wish, or a built-up area.

If you think this is using relations as categories, then route relations 
are that as well.

So let's be clear here: I'm *not* proposing to add all roads with 
maxspeed=50 into one relation (that's a category), nor do I want all 
roads inside all built-up areas of one country inside one relation 
(that's a category as well).

I want one built-up area represented as one entity: a relation (as 
that's how traffic legislation handles it: a single entity) (that's not 
a category), or all roads inside one zone 30 into one relation (that's 
not a category), or all roads inside a parking zone into one relation 
(that's not a category)

More clear now?
