The excellent UK paranormal Database has two new possible time=slip cases:
"Location: Chelmsford (Essex) - Regiment Way roundabout in Beaulieu
Type: Haunting Manifestation
Date / Time: 2018, 00:00h
Further Comments: While driving along this road, two people slowed down to ascertain their location. As they approached the roundabout, both spotted a man wearing Victorian clothing, including a small top hat, walking along the side of the road. After a few seconds, the man vanished, leaving behind mist."
And one that sounds familiar:
"Location: Lambourn Woodlands (Berkshire) - M4, between Junction 15 & 16
Type: Haunting Manifestation
Date / Time: Circa 1990, 00:30h
Further Comments: A witness passing along this road noticed a group of people walking towards the motorway. Even though the ground was uneven, they moved as if on a smooth path. The lead figure, a woman wearing a maroon Victorian dress with matching bonnet, held aloft a ridiculously small umbrella. A man close behind appeared to be listening to the woman, and wore a top hat."
