Regardless of how busy the road your reversing into is, your still going against the flow. This is more an issue in a larger vehicle than a car, but it’s a blind side reverse too - much easier to reverse around a right hand corner as you’ve got much better visibility on that side. Everything about it seems a bit daft and something you would avoid unless completely necessary IRL. Do a turn in the road, or swing around to block the road and reverse straight back into the driveway or whatever - you have control over what the other traffic is doing then (i.e. They have no choice but to wait for you)
I don’t think reversing through a No Entry sign is allowed, either
