Description of the bug

When two robots operate in the same lane, they sometimes experience unnecessary waiting periods. These delays persist until they are forcefully aborted by a 30-second timeout, which negatively impacts system efficiency.

Steps to reproduce the bug

1. Deploy two robots running in the same lane with a waiting mechanism.
2. Observe their behavior.
3. Notice that both robots sometimes remain waiting for traffic while nothing is blocking it .
4. The wait is only aborted after an extensive 30-second timeout.
