2scents: Puleaze. I’ve seen it happen quite often over a period of many year. And always for just enough time for the driver to turn on and off his lights & sirens for exactly the time it takes him to pass the traffic jam.
We both know it is not that often that a call comes in and is cancelled 45 seconds later. And the few times it does happen, how coincidental that it usually happens when the driver just so happens to be in a traffic jam rather than experiencing normal traffic.
