Waze offline cache
Feature request: Automatic offline fallback for active navigation
When a user starts a route while connected to the internet, the app should automatically cache enough information to continue that active trip if mobile data is lost.
The phone would still have GPS, so it could continue following the already-calculated route locally without needing live traffic or server-side routing.
Ideally, the app could also cache a small road graph around the route. If the driver misses a turn while offline, a lightweight local routing algorithm such as A* could find a path back to the original route rather than requiring a completely new online route.
When internet connectivity returns, normal live routing and traffic updates could resume.
This would make navigation much more reliable in areas with temporary cellular dead zones without requiring users to remember to manually download offline maps beforehand.
