routeSampler only uses the routes that you already provide as input. Of course, you can use implausibleRoutes.py before running routeSampler to analyze and tailor the input.
Looking at your scenario, I see the following issues - uncoordinated/unjoined traffic light in the city center - missing acceleration lanes at your motorway on-ramps. This turns highway on-ramps into normal junctions and reduces flow significantly. (add ramps manually or rebuild your network with option --ramps.guess. This may split some edge which invalidates routes so afterwards you will have to regenerated your route files or repair them with duarouter option --repair regards, Jakob Am Mi., 8.
