I seem to recall that the driver was the father of #1 son who was born the previous evening whilst we were on the Inter Island ferry. Reflexes were a bit slow the next morning and the off was after the finish line.
Cookie, who we had caught up on went around the corner, we didn't.
Big lesson learnt about not turning the brain off when you cross the finish line and that you have to retain 100% concentration until you come to a stop after the finish.
Unfortunately that photo and the acompanying story made it as far south as the Greymouth newspaper which came out that afternoon about 6 or 8 hours before I thought to get to a phone.............Another lesson !!
Took a while to get it out of there as the tow truck did not have a winch cable long enough to reach the car.
