You do get gaps in the network, to the extent that occasionally a section of a trunk road has been replaced with a short section of motorway. Unavoidable, but not really a problem. Both are rendered in a way that indicates they are preferred routes and humans looking at a map are good at spotting that there is a continuous route even though one segment has different legal/physical characteristics. Where the problem comes is with those who insist that a trunk road passing through a city or large town should be tagged as residential. A good example is the A487 passing through the centre of the city of Aberystwyth: https://www.openstreetmap.org/?mlat=52.4163&mlon=-4.0802#map=15/52.4163/-4.0802 In my opinion, tagging the trunk roads (and secondary roads) passing through that city as residential would be very unhelpful. -- Paul
