They might not have even noticed if they were old?
A similar thing happened to me earlier where an ‘old biddy dear was trying to park in the space in front of me, whilst I was parked and on the phone.
She drove in forwards and I heard a scraping as she was failing to get in at the right angle- so I beeped to get her attention and told her to move back- but she could barely see over the steering wheel, and just completely ignored me, like I was being unreasonable by asking her not to continue slow motion crashing into my car!
She didn’t stop, and put a nice scratch in my bumper.
I tried talking to her, but she was just muttering to herself and wouldn’t open her window and wouldn’t get out.
This is why old people shouldn’t be allowed to drive.
