# Logic flaw: The algorithm prioritizes Crit'Air sticker purchase warnings in France over suggesting an automatic reroute

When planning a long-distance route (e.g., 2,400 km) crossing France without the Crit’Air vignette configured, the algorithm insists on routing the car through the center of Lyon (ZFE), only issuing a warning to buy the sticker.

As a driver, if I haven’t entered that sticker, I expect the navigation system to automatically redirect me via the restriction-free bypass (A46), even if it involves a small toll (managed with my Via T). The system prioritizes the free section through the center over the vehicle’s legality, forcing manual stops to be configured. There should be a button to “Avoid emission zones if no badge is available”.

**Additional details for case replication:**

- The vehicle is configured in the app with **environmental badge B (Spain)**, an **Umweltplakette (Germany)**, and an active **Via T** device.
- Despite being allowed to use toll roads, the algorithm prefers the free route through the urban center (which requires Crit’Air) instead of automatically tracing the bypass via the **A46 North (low-cost toll)**.
- Please escalate this behavior to the global development team, as the current screen warning does not offer a real alternative for safe navigation for international transits without a local badge.
