About eight years ago, I got a speeding ticket on the Pukehina straights. I didn't even realise I was speeding, it had crept up on me.
I certainly don't think I was in any danger of hurting myself or others, but the sting of a fine soon taught me that breaking the law wasn't worth it and I've become far more careful about my speed.
That in itself proves the ticket did its job. I was caught breaking the law, was duly punished and have learned my lesson.
Since that time, I've been called out a handful of times to cover serious crashes on that safe-seeming stretch of road.
It doesn't matter how good a driver one is when it comes to speed. You can be the best driver in the world cruising along a straight road at 120km/h. But if a driver doing 80 falls asleep, crosses the centre line and smacks into you head-on, your speed can be the difference between serious injury or death.
The faster you go, the bigger the mess, even when you're not at fault.
