Maybe somebody can explain this. has nothing to do with ghosts but it still puzzles me.
Years ago, I was driving on the highway. Just before I took the exit I passed a much slower car (wreck). Full with stickers, different colors etc. I took the exit, got on another highway and suddenly, I passed that same car again

It's impossible for this car to be on that other highway before me, because it was going another way (didn't take that exit) and I did not see this car passing me (if it should have taken the same exit).
