Moin, in the Wiki the != test is described as follows: highway!=motorway This will be true when the highway tag exists, but it does NOT have the value motorway.
From my understanding this should read like
highway!=motorway This will be true when the highway tag exists, but it does NOT have the value motorway, or when there is no highway tag at all. Shall I correct the description in the Wiki or must I correct my understanding of the != test? Gruss Torsten

Yes. That is how it works. Wiki is often outdated or incomplete, or sometimes even wrong...

This is correct. highway!=motorway returns true exactly when highway=motorway would return false. It looks like I wrote that sentence on the wiki, I have no idea what I was thinking - sorry. ..Steve
