It is incorrect for the routing algorithm to use that path if the
routing was done for car traveling. This seems like a bug in the router,
but the actual route should be provided to better judge the case.

One of the first advices you generally get as a OSM newbie is "do not
tag for a renderer", I guess it should/could be expanded to:

"do not tag incorrectly for a certain renderer/tool to work as you'd
like, but instead report the bug of that tool."


Please provide a Permalink to the route you're seeing (see the
"Permalink" link on the right side of the map once the route is
calculated, right under "Length").

Generally that is due to incorrect underlaying data, again, a permalink
to a minimal route that shows the problem is what's needed.

Indeed.

Not that I know of, but you should make sure the data is correctly tagged.
