" Generate an asynchronous driver distraction detection application that dynamically adjusts vehicle behavior based on the driver's distraction level. The system should:

- Continuously monitor the distraction level and compare it against a predefined risk threshold.
- If the distraction level exceeds the threshold, turn on the hazard lights and set both left and right fan speeds to the maximum.
- If the distraction level is below the threshold, turn off the hazard lights and set both fan speeds to the minimum.
- Ensure that the system is non-blocking, with an asynchronous loop running at 1-second intervals.
- Use proper condition checks to avoid redundant actions (e.g., if the hazard lights are already on, don’t turn them on again)."
