Hi @imran.hamblinNZK78, I hope you're doing fine. My insights:
In my opinion, the parking maneuver for that kind of vehicle shouldn't be considered a reverse maneuver. You found it difficult to park that vehicle while doing the simulation because that's indeed what will happen in real life, considering that the coupling offers poor control over the direction it has to go towards.
If the stall has to be traced as you have it, the vehicle should have more space to the left part of the layout of the parking lot to position itself better to go backward.
Best regards!
