Well so long as You’re both ok, & there wasn’t any damage to your van it appears that you only lost a cpl of hours sleep thank heavens,
How blinking annoying & Unsettling for you though.
Thankfuly thease kinda incidences are very few n far between, Imust be one of the very lucky ones as I’ve Never encounterd any Hostilities or confrontation, but it’s just an odds game, Look how many cars go to a Supermarket everyday & Then look how many get damaged!. (Not the point, & of Little Comfort But —-)
It’s good that you got the Reg though, & Again Thank Heavens Your both ok.
