Motorways are perfectly relevant since they are identical to pavements  (which this is) in terms of legality of cycling. In both cases cycling is illegal so the appropriate tag is bicycle=no. Simple, unambiguous and understood by everybody.

The only difference is that you personally seem to have a problem with the law with regard to pavement cycling evidenced by multiple examples of you mapping pavements (and even places where cycling is explicitly prohibited) as cycleways - and taking issue at great length when that is corrected.
