When setting the trans brake most feel that your car won't and can't move. When staging you set the trans brake, during that time you are waiting to release the button. If that car with small tire moves .030 or .050 or .100 for what ever reason, more back up pressure applied than forward, wind, etc ... do you think anyone would be able to actually see that movement, but that may be all it takes to light the red light by allowing enough of the beam to make contact to the outside cell.
just a crazy thought ...

Right, Chuck. ...and on top of that, the car shakes from being on the rev limiter.
