After driving through Sydney in 2013, my impression is the drivers are twice as bad as those in Toronto , most cars have dings or other damage .
You hit the worst part of living here on the nose. I've only been here a few years (New Jersey is my indigenous land), and there truly are a lot of great things about living here. But I'm a cyclist, as in I ride a bicycle. I often ride the 20km's to work on my bike, and Sydney is worse for close calls than any place I've ever lived.
One area that it's particularly bad in is people tailgate like crazy - it's not terribly unusual to be driving along at 80kph, and have someone sitting less than two meters off your rear bumper. Unfortunately, there is not a lot of police enforcement against things like that.
We're moving to the southern part of the Gold Coast, soon, and I'm very much looking forward to it. We've spent some time up there, and it seems to be less of a "rat race" area, people seem a little more interested in being considerate to other people, and I'm hoping that carries over to how people handle themselves on the road.
Don't get me wrong - Sydney has a lot going for it, and I'm probably just a cranky old man (49). The older I get, the farther away from cities I want to be, so it's probably me, not Sydney.
