Lane splitting yes and passing on the left NO, sorry slow lane. Make it illegal to pass a vehicle in the slow lane which would get everyone to move over rather then sitting in the middle or passing lane as they would be eligible for a ticket as well. Driving out of Melbourne today on the M1 I mentioned to Jane that these people drive like Canadians jamming up the middle lane going slow in the fast lane forcing people to go to what should be the slow lane even though there are signs saying move over, just like in Canada.
