There is plenty of evidence both video and people right there to prove one way or another if DeFrank's car moved. My opinion for the zero it's worth is his car didn't move.
There is no evidence so far to prove that a camera flash did indeed cause the false red so it's NHRA's "that's our story and we're sticking to it" once again. This isn't an isolated incident and getting to the truth of the matter would be a big step in getting it fixed.
