I've been done for speeding a few times, and yep I was speeding [bike and car], doing the 10% thing [110 n a 100 zone and then just going over the 110 as well, down hill etc]. I objected to the fact that I was the only person on a lonely straight excellent surface road with good visibility, but shut up and paid up, no real alternative to that.
But what I really want to say is that the various speed limits [110, 100, 80, 60, 50 etc] are only an upper limit not a set speed. We all tend to forget that on a 100km/h road, you can do 90km/h [boring I know, but bare with me]. So when the cops decide 'zero tolerance' and we are doing 105, we are in the wrong, we don't have to sit on 100km/h exactly, we can all cruise at 95 and a have a buffer margin.
Me, I'll probably keep doing what I always do and whinge at all the 95'er's holding up the traffic, but at least I realise that I do have an alternative, its just that that alternative is not that attractive to me [which proabaly means that I'm willing to pay the price if I'm caught]!
So if your caught speeding, then you have made a conscious decision sometime before it happened to take that risk, and only have yourself to blame [like me].........
