What about actually improving directions, not sending us through barely usable roads in Mediterranean islands, if we can consider them roads at all. Or shortcuts that might be interesting in a computer game, how the RTS units select their path, but hardly so when driving through a medieval village, instead of the somehow longer circular road that everyone should use.
In this context (driving in central Europe) I've found Apple Maps to choose the conventional route more often. The trip may be slightly longer but more enjoyable, for the exact reasons you mentioned. Google Maps indeed seems to be weighted towards stressful shortcuts.
A month ago I was driving hundreds of kilometers across Poland, and Google sent me from a freeway through a comfy road to a literal dirt road with holes, which after ten kilometers led us back to a large asphalt road. That was fun!
