I can honestly say I’ve never tried the parking assist to park ‘around the corner’ I have put the car straight to the parking space (just pull back to park) and that worked fine. This also means you can get out while half in the space and then move the car back into the space fully knowing it’ll be straight.
In theory there’s nothing wrong with pulling up, getting out and getting the car to park, although I’d expect there’s a pretty good chance it’ll not park perfectly, which in a tight spot is pretty much exactly what you need to minimise the chances of getting some idiot opening the door into your car.
It’s not something I’m likely to be trying other than just to see if it can and that’ll only be where I can hide in a quiet area without risk of annoying other drivers.
I'm Autistic, if I say something you find offensive, please let me know, I can guarantee it was unintentional.
I'll try to give my honest opinion but am always open to learning.
