Wheels and driving

78 records: 0 read sources that cad-agent's rules and checks may cite, and 78 records catalogued from the Reference Map, not yet read. Wheels, hubs, tyres and the drivetrain that turns them.

Catalogued records are search snippets: their numbers are the authors' claims and their licences are as the map states them, unread. Cite one only after reading the source and promoting it (how).
