You're welcome, Charles. Glad I could add some help.
So, the car in the photo (which I have added a red arrow pointing to) is the car in question, and Royell is stating that it is parked against the northernmost curb directly in front of the TSBD-not against the curb that forms the peninsula where the traffic light, lamp post, and highway signs are situated?
No Steve, I believe that Royell claims that the car you drew a red arrow pointing at is not yet there in the Weigman footage but is traveling towards that spot and doesn’t show up until about 20-seconds later in the Darnell footage.
My opinion is that it actually is there in the Wiegman footage but is mostly hidden by the crowd on the island and Elm Street. There is either an optical illusion that has fooled me and some others or I am simply wrong. I will try to show it to you in the following images. Royell apparently doesn’t see anything on the island side of Elm Street in the Wiegman footage. While I think I am seeing two different cars, James Hackerott apparently thinks there is only one car and believes it is 5.5 feet further west than I think it is.
In the following image I have drawn a yellow outline of where the right rear taillight bumper appear to be to me. If you look back at the unmarked up photo, please notice that the odd shape of the reflection of the sun on the car on the TSBD side of Elm Street Extension is similar to the taillight/bumper of the car on the island side.

The following image is from the Wiegman film and is the one we are discussing. I added a yellow outline of what appears to me and some others to be the right rear taillight & bumper (similar to what I outlined on the photo you provided). I think the car on the other side of Elm Street Extension is a different one due to the different angles. However, I believe the concept is still the same.

I know it is difficult to “unsee” something like this once you believe in what it appears to be to you. We apparently have three different interpretations that each one firmly believes in.
