Really odd jittery reversing on a three-point turn and some kind of reversing audio signal which sounded like an air raid siren. (This is an internal one with all their windows closed, not an external one like you get on large vehicles). Must’ve addled their brain.
Seemingly extremely nervous driver which made vehicle handling erratic.
Drove down our road, did a very tentative three point turn, crawled back up to the main road, then sat there dithering (barely any traffic), reversed back a bit, then sat there with the reverse light still on, for about two minutes, before carrying on the way she had come.
Probably lost, but really not doing herself any favours driving so timidly.
