Yes, and this can be tricky to pick out when you're just eyeballing an
area. I've been using the JOSM validator after doing a CTRL-a to
select everything I have downloaded. It is kind of noisy but just
looking at crossing ways and orphan nodes seems to find a lot of
problems.

I thought there was actually a debug tool that showed crossing ways
but I can't seem to find it now. I may have been thinking of the OSMI
"Geometry" layer but it doesn't show crossing ways.

I have been using my map of ways with a oneway tag but no highway tag
to find problem areas. Chances are wherever one of these ways exists,
there are probably more things to fix nearby. I just updated it last
night. Adding it as an imagery layer in JOSM lets me zoom in and
download a problem area quickly.
