This vid really makes you realise how close the Bench is to the car parked. Have the police ever confirmed what time the car arrived? I’m wondering whether it could be feasible that PR parked there prior to Grey Beard chap stopping to ask LS if ok and actually heard him pull over, get out of his car and speak to her and more importantly did he hear LS reply? If he was under the impression that a late night bus was running as on other nights, was he parked up ready to watch for student girls to follow? Is this why he didn’t approach LS sooner, as expected she could have possible company at any moment. I could imagine that once LS realised the bus hadn’t dropped of any fellow students, she would start sobbing at the thought of having to wait another hour or even realising there may be no buses running. A lift from a chap not too much older may then have become more welcoming. Just a thought...
