Irrelevant.  I never said you had to use relations.  In fact, I said you
don't.

I wouldn't call the use of relations "nutty", though.

Fine.  You can add "maximum height" along with "maximum speed" to your list
of lane-specific data.

I don't find it very important, but if you want to allow for this, without
messing up anyone else, feel free.

Yes.

Yes, I do.  Have you read what I said?

So you think those examples should all be represented as a single way?

That's horrible.

The maximum speed of a way is the maximum speed of that way.  If you want to
*also* tag lane speeds, feel free.

One bridge or two?

If it's one, then you are off-topic.
