Several years ago my elderly mum, a dementia sufferer, absconded from the hospital where she had been a patient. Somehow, clad in a nightie, dressing gown and slippers, she got out of the huge building, out onto a very major road, to a bus stop, boarded the bus with no money or card - presumably the driver just waved her through - got off at the right stop, and managed to walk home, crossing a very busy dual carriageway en route. The first my father knew was when she walked in through the front door. The whole journey must have taken well over an hour but she wasn’t missed by the hospital and, as far as we know, nobody she saw made enquiries or phoned the police. So YES Jaffacake2 you absolutely did the right thing.
