Depends on where you are. I don't remember seeing inaccurate crossings in the Netherlands, and scrolling over some roads just now (some rural, some in towns, some in cities), it matches 100% with my memory (true positives and true negatives).

Germany also has good data, but I drive there much less so I can't vouch for it.

Belgium on the other hand... I haven't yet found missing roads, which is surprising given what the map looks like.
