The new script is up now.

I used Maryland as a test case

In Maryland the number went from 21 roads it couldn't expand to 1.

But that's 20 out of the ~70k it *was* able to expand, so either you
could say it handles 99.5% of all previously unexpandable roads, or it
handled .0003% of all total roads.

"As low as possible", but I've been generally able to handle the edge
cases I've seen, either by doing the right thing, or by punting and
doing nothing at all.
