Except he didn’t do anything like that. He just hit the brakes.
I mean, maybe you want to imagine some inverted anvil, but that’s not in the movie. And to me, it seems silly to imagine it.
Occam’s razor suggests that there’s not some secret complex explanation explaining how it works… Nolan just filmed a scene that doesn’t really make complete sense, because he wanted to film a cool backwards car chase.
I’m not sure there’s any clear indication that the car itself is not inverted, but perhaps it is.
And if so, then I guess you are correct that the intent explanation wouldn’t explain it… but that leaves us in a situation where there’s no explanation at all.
Like I said, I didn’t even think it was a good explanation… merely that it could possibly have explained stuff.
I don’t think I necessarily buy into the notion of a lack of free will in the movie.
You can perceive the notion of the timeline existing already as a lack of free will, but only if you limit your perception of the individuals as only existing in a singular point of time.
If you extend the idea of the individual beyond a single instant in time, to be their entire existence throughout the entire timeline, with ALL of that being “them”, then you can still have free will. It’s just that the entity which is expressing free will is not the 3 dimensional being that exists at a single point in time, but is rather the 4 dimensional being that exists across all points in time.
So, in that explanation, you’re still making your own choices… it’s just that you’ve already made all of them. But they are still your choices, and thus you still have free will.
