———————————————————————————
When GPS signal is lost in long tunnels ABRP get confused and stops following the road like normal GPS after like a minute. It should be locked to the road at the speed limit during the entire tunnel and then wait at end if driver was slow. This is how most GPS do it.

It will also do weird rerouting after signal is back because it thinks the car is in a completely different location.
