Not riding but driving alone... I was dropping my ex and her pal to Dublin airport from the southeast where I live, on the newly opened Motorway about ten years ago. We were alone on the motorway as it was about 2-3am.
we came to a garda (police) car at an exit and were flagged down; the officer told us there was a fatal accident a bit further up the motorway and had to divert off but could get back on after about 5 miles.
I continued the journey and dropped them off at the airport, then turned around for the 2hr drive home, as i was on the opposite side of the motorway I passed the accident scene which was being cleared at around sunrise...then things got weird.
As I drove away from all the floodlights and flashing blue lights at the crash scene into the semi-darkness again, I could hear someone softly crying and sobbing in the back seat of my car! Needless to say, new underwear was almost needed! I swung into the hard shoulder, threw on all the lights/hazard lights and interior lights and jumped out and looked in the back of the car and the boot (it was an estate car).....no one else in the car!
The drive home was very eerie..
