@albert-renting that sounds about right.
My own interpretation is that routes are map-item-based (roads, junctions, roundabouts etc) entities describing the path. These items are highly accurate. The route thos describes an ideal path.
Tracks are basically breadcrumbs on a wiggling line. You can fabricate a track yourself by storing your GPS-location at regular (short) intervals as you go along, or a track can be made synthetically by calculating breadcrumb locations from map data. The former track-making method shows your GPS's idea of where it is - usually with an ccuracy of a few meters, meaning it appears to be all over the place. The calculated track is bang-on.
Your satnav knows how to get from location A to B using its internal mapdata. When you tell it to guide you to B, it calculates a route. It then shows you the road (its GPS is not that accurate, so it synthesizes your location to be bang-on on the blacktop) you need to go. Routes are map-based.
Tracks are more like dots on white paper. Location yes, but map items no.
Try generate a track from A to B.
Then drive from A to B while recording a track.
Compare the two. They differ quite a lot.
Synthesized vs recorded. Ideal vs actual.
GPS inaccuracy revealed.
