When I'm driving my car and listening to an audiobook or podcast, I find that if I rewind it a couple minutes, my brain will flash back to where I was driving when I heard it the first time.

really weird.

additionally, and somewhat unrelated... The best racers know the course. They can sit back, close their eyes, drive the course in their mind, and open their eyes. If they are missing parts of the course in their memory, they have more to learn. If they time this exercise the closer they are to a lap time, the better they know the course (and the better chance they have of driving it well)
