There are two forms of on-road cycle tracks under the Roads Acts. Where the line is continuous, the lane is dedicated to cyclists and vehicular traffic should not cross the line and enter the track. Where a broken line exists, the track although also dedicated to cyclists is only advisory to vehicular traffic which may enter if safe to do so. The continuous painted line is a clear legal separation between vehicular and cycle traffic. It is just a cheaper separation to a kerb or row of bollards.

East of Idrone Close are the private rear gardens of Coolamber Park where aerial photography indicated a continous boundary from no 35 to 38 Coolamber Park

I consider driveways are hyper-detail and only a small minority are tagged correctly. I also consider your allegation of map sabotage as potentially defamatory.
Most driveways are mapped very inaccurately. The tagging by default allows access to all; foot, motor vehicles, bicycles and horses. Usually there is just a node point at the end, but I’ve encountered them joined to buildings, walls and administrative boundaries. Unfortunately more are being constantly added. I do not add driveways myself. I edit them as private where I encounter them and I preserve the continuity of the dedicated pedestrian footpath where one exists. If no public footpath exists, I leave them linked to a road, but tagged as private. I disconnect them from buildings etc. where appropriate and add a ‘no exit’ tag to the end point.
Driveways are virtually all private rights of way. The private right of way usually extends only to the back of any footpath that exists. Footpaths where they exist or where provided with a development granted planning permission or directly by a public body like a local authority are public rights of way dedicated for pedestrian use only. The crossover between a driveway at the back of a footpath and the road carriageway still has a dedicated pedestrian priority right of way and there is only an easement to permit vehicles or others to cross. Pedestrians still have a dedicated right of way on a crossover that has precedence over all other users who must give way. This for the protection of pedestrians. Vehicles, cycles and horse owners have virtually no defence for any conflict or injury to pedestrians on a dedicated footpath. Footpaths are connected to the road network at marked and unmarked crosswalks, thus ensuring that there is connectivity in the map network [everywhere there is a dished kerb there is potentially an unmarked crosswalk]. It’s unfortunate that so much focus with OSM map edits reflects a vehicle centric prejudice, and not pedestrian safety considering they are more easily get killed by vehicles. OSM tagging seems to forget drivers are pedestrians whenever they get out of their vehicle, and most vehicles spend around 95% of their life parked.
A separate problem with driveways indicated as giving access to all is the implied infringement of private property rights. Printed Ordinance Survey maps in Ireland and the UK all carry a disclaimer that the indication of a route on a map cannot be taken as proof of the existence of any right of way (or access). This has arisen due to case law where maps were offered as evidence of a right of way and hence a public right of access, or an obligation of the state to maintain the right of way.
Rights of way in Ireland are created in common law by deeds of dedication. This requires both a grantor and a beneficiary to be identified and details to be recorded with property title deeds. The Planning and Roads legislation also address the establishment of rights of way and access which must be publicly declared.
My driveway is part of my private property and I would not welcome any map that implied a right of access for all to my property. No driveway in my estate is marked on OSM and there is no reported failure of GPS navigation as a result. Driveways though hyper detail, should be private, or permissive if the intention of the property owner is known. OSM does not have an unambiguous capacity to indicate by disclaimer that access shown may not in fact exist.
Footpaths are a very small part of the public realm where pedestrians have dedicated and exclusive priority and are entitled to be there in complete safety, segregated from vehicles, cycles and horses. It is at crossovers, marked or unmarked where a pedestrian needs to exercise caution. It is wrong that driveways should erode a dedicated pedestrian priority.

The Planning Authority prepared a naming scheme for the distributor roads in the 1980's that would have been later added to the County Road Schedule - then Dublin County Council, now Fingal County Council. These are generally the roads with no direct access so no or very few postal addresses. I think one of these roads should be Blackcourt Avenue, - Road Schedule for confirmation. Its unfortunate that Councils no not make county road schedules readily available to the public
