[Tagging] Highway barrier

All interesting arguments but if a highway has a barrier, won't all access
be treated as blocked (access=no) by _most_ routing software? I realize one
can accommodate  almost anything with appropriate styles and rules but how
can one know in advance? I guess what I'm saying is, there is a risk that
these ways will become non-routable if I put a barrier tag on them. As long
as you're traveling in the correct direction, you've got nothing to fear
(Where have we heard that before?)

I know this: I will never drive a motorcycle in this city, and especially
not a night. You could end up dead on one of these.

By the way, for those of you wondering; these are permanent devices and are
built into the pavement.
