It does not matter where he car is really.. He got out and was staying in that general area.. He walked across on the sidewalk and came back. It puts him right where he said he was.
TM says he is somewhere else entirely and then is there when the fight starts..
You can see it differently but it fits with the evidence that it was TM that doubled back and not GZ. He is where he said he was... OMO
I see this. IMO
