So, a month or two after it was legalised in Queensland, I filter as and when it seems appropriate on my commutes. I prefer going through the middle than up the left, though I know a lot of people are the other way around. Law is 30 km/h max and I see a lot of people going a lot quicker than that. I don't judge 'em, but I also won't judge the cops if they pull 'em over. Use the new freedoms, if you decide to bend the rules you man up and take the consequences. (I'm consistent - when I used to filter and split when it was illegal I considered the odd fine the cost of doing business.) This is not my point, though: just wanted to note that I'm enjoying it. I think the attitudes of the drivers haven't changed all that much. About the same amount close the gap on me, and open it, as before. Most of those who close the gap turn out to be texting rather than intentionally malicious on closer inspection. Interested to hear others' experiences of legalisation.
