While it would be awesome to have all the HO scale vehicles inside the LDraw collection, I do tend to agree that parts with system connections (studs, pins etc...) are the most interesting ones to add since LDraw is primarily used to model things that people can build with LEGO.
My queries seem to filter out most vehicles or other non-studded parts, so it is hard to know which ones are most common and should be tackled first,.
Even with my queries, if we look at the 'most common' parts for an era like 1950-1960, some LEGO "elements" that are definitely not bricks appear pretty high on the list, like:
- #60 - tplan02 - https://rebrickable.com/parts/tplan02 - Masonite town plan base that you can build your town on top of.
