Too many to count, to be honest. I've lost my licence three times all from speeding. The last fine I got was from a speed camera but no points...although I thought I might've gotten done the other day going through an intersection on Tonkin Highway because I was distracted for a second and I think I was going 86, I'm not sure.
I'm stoked because I've finally just got all my points back after my last big fine a few years ago. Although the quickest way to get them back is actually to lose your licence, you don't have to drive for three months and at the end of it you have a shiny, new 12 points as opposed to having to wait three years to get them all back!
(Disclaimer: I'm not suggesting that anyone should got out and lose their licence to get their points back, it does suck not having a licence for three months!)
