The parkways do not all have RIROs, especially not ones as blatant as on Ocean Parkway and the Taconic. Your changesets have set multiple roads as motorway straight through full intersections (see https://www.openstreetmap.org/#map=19/41.180799/-73.758318 https://www.openstreetmap.org/#map=18/41.974509/-73.749359), which is completely unacceptable for a motorway. Additionally, it is well agreed upon that in the US, RIROs are not allowed on motorways (https://wiki.openstreetmap.org/wiki/Key:expressway#How_to_decide). expressway=yes is what distinguishes a surface road from an expressway in cases where a road doesn't qualify for highway=motorway.

Notably, I have the Saw Mill as a trunk expressway from the Cross County all the way to the northern end, since even in the controlled access segments, the design is deficient compared to the other nearby motorways (e.g. Thruway, Sprain, Hutch). Also, I set Mosholu Parkway to a primary expressway because based on the way it is used (using local knowledge), it is not important enough to be at the trunk/motorway level.

Otherwise, you made the BRP a motorway from the Sprain to Scarsdale Road, which I disagree with given local knowledge of how that road is to drive on. Just because it is controlled access for a short period of time doesn't mean that it is motorway quality.

I reviewed each of these changesets by hand before reverting, so please let me know which ones are proper in your eyes and I will be happy to discuss further.
