Noticed a strange thing today.
One car was in the pit and left pit at the "Go" call. At the same time the race was paused. What happend was that the power was not cut on the lane with the car leaving the pit. The power was cut at the other two lanes.
Its an analog track with webcam detection (zone trigger) for both pit and lap detection. A phidget card is controlling the lane power.
I have tried to replicate the problem and it happen every time if you leave the pit at the same time as the race is paused. Not a major problem since the chance for it to happen again is quite small.
