Dont know if this has come up before, but I think the idea of a percentage based speeding fine system would be a good one. I've always thought that the current <15, 15-30, 30-45 & 45> (I think that's it) does not represent the nature of the situation. I think doing 20 kms over the speed limit in a school zone or residential area (like 60 in a 40 zone) is a lot more dangerous than doing 20 kms over the limit on an expressway or highway (like 120 in a 100). I know the maths would do the average police officers head in, but surely those clever little speeding fine machines could calculate the figures! Question is, what percentages would you use? Thoughts anyone?
