Motorcar vs (passenger) car
The use of the term motorcar might be somewhat confusing, but apart from the specific meaning of the -ambiguous words used, the explanation of the tag motorcar=no shows that "motorcar" refers to the wider category of "double tracked motor vehicles" and not solely to the sub-category of (passenger) cars:
- Note that motorcar=no means 'no entry for any power driven vehicle except two-wheeled motor cycles without :side-:car', thus implying hgv=no, motorhome=no etc.
Otherwise a road that would only be openend for (passenger) cars, but not for other double tracked motor vehicles would have to be tagged with [motorcar=yes;no]
Altough I'm not German, it shows that the German language and Wiki for motorcar and is more precise and explicit in this case:
- Offizielle Zugangserlaubnis für Kraftwagen und sonstige mehrspurige Kraftfahrzeuge, dazu gehören LKW, PKW, :Busse, Trecker aber keine Motorräder.
