There’s a Honda right around here, same make, model year, trim and color as ours. What’s more, only the last two digits of the license plate are different (theirs ends in -50 instead of -48!).
One time it was parked right next to ours, at Lake Hodges, when I returned to the trailhead parking lot from a walk with Toni. I thought I was hallucinating! Another time it was parked in the Costco parking lot and I was going crazy, because neither the remote nor the key itself would unlock the car.
I’ve learned to approach what appears to be our own car with caution on public parking lots.
