Right...but either way, left and right are not very useful.  And which
side's left and which is right?

If I'm on Foo Street, I don't much care which side #1542 is on, and
which side #1565 is on.  Getting to the correct block of the street is
sufficient.

If we take it as read that that aspect of maporama's visualization is
useful, yes.  I don't think it is.  Again, it doesn't matter which side
of the street the numbers are.

For navigation or "object selection" (e.g. clicking on a street section
in roadmap) blocks are more interesting than segments or whole streets,
really.  "All segments between two junctions/intersections" is what I
mean by "blocks", btw..

Which end is the start, which is the end?

Well, it doesn't have entire roads yet, either...but before saying that
roads are the smallest useful unit above segments, as the original post
and immediate replies seemed to say, other things should be considered.
