Time travel rules aren't even consistent
So, based on two things:
1. Original videotape with him in it
2. Car being fused in the wall even before they sent it back in time (seen in the video)
It sets up time travel rules of things being set in stone, as in, anything that involves time travel has already happened (as it happened in the past) regardless of the sequence of events.
Then it contradicts itself with a tonne of stuff - biggest being the ending, where they change the past and create a new sequence.
Simplest way to visualise:
