Apologies @
Adam1user. Rob is correct in that there are no lane markings on the far side of the intersection - I thought there was and I was wrong.
It can be clearly seen in the video that the roadway is two lanes wide and the left side is blocked by parked vehicles. It can also be seen that there are no lane markings until around 1:12 into the video, which means that on the far side of the intersection, there is only one lane.
BUT...
Street View shows that on approach, lane markings begin just before the intersection. It also confirms there are none on the other side. Without any markings related to turning (left turn only for example), the purpose of the short left lane is for turning left or for passing vehicles that are waiting to turn right. Unfortunately, there's nothing that says you can't go straight ahead from the left lane and that means that idiots like this guy use those situations for overtaking even when vehicles in the right lane are going straight ahead.
So it appears that the "merging" rules do actually apply here. But regardless of that, there are still other issues. The Corolla still has to give sufficient indication - which it didn't. Instead, the Corolla doesn't indicate until it starts moving across - and that's not just failing to indicate, it's also dangerous driving, because moving across without indicating early enough nearly caused an accident.
The recording vehicle simply could have pulled out earlier and let the Corolla go, but with no earlier indication, they didn't have to under the law. Did the recording vehicle do enough to avoid a collision? Yes - because there wasn't one. Did the Corolla? Yes, but only after causing the situation in the first place.
It's therefore pot luck as to what the Police would say about it, because common sense says that the Corolla either should never have been there to begin with, or should have indicated much earlier or given way. But unfortunately, far too often we see that the law and common sense are two entirely different things.
Anyway, there's a whole bunch of issues here. One is that the Corolla appears to go over the stop line when it creeps forward - the recording vehicle may have as well but it's hard to tell. The next is how late the Corolla indicates and that it moved right regardless. Another is that the recording vehicle swerves a few times - there may or may not be enough circumstantial evidence to claim extenuating circumstances - the problem being that the Corolla is not always in view. Another is that after stopping, the recording vehicle appears to leave and change lanes twice without indicatiing - the left indicator goes off when leaving, but we don't see any more flashing when moving right then back to the left. (We should be able to clearly see this on the ground as we did earlier.)
In regard to the noise, the video doesn't show anything on the road that could have caused it, so assuming the owner has photos of the damage, I would think there is enough evidence to conclude something was thrown at the vehicle.
For anyone who's interested in taking a look at the markings, it's pretty easy to work out that the vehicles were heading south in Wyndham St, Alexandria, NSW and the cross street at that first intersection is McEvoy St.
Here's a Street View that begins just before that intersection, showing where the lane markings begin and how short they are:
