———————————————————————————
ABRP (much more so than other navigation apps) behaves very erratically when GPS accuracy is low. The car spins wildly at stops, frequently jumps to/back from nearby roads, replans constantly and generally makes the route very hard to follow.

This occurs most often in mountainous areas where fewer satellites are visible; the overall location is still fine, but it feels like ABRP is not taking the GPS accuracy estimate into consideration when smoothing the track such that it exhibits very high jitter in the vehicle's position.
