Re: 40' width is the roadway for traffic. Really, Andrew. This is 101 stuff. "The width of each concrete roadway through the Plaza is 40 feet." (CE 877) Houston Street (and Elm and Main where they begin eastward of Houston) are wider, at 60' width per Google Apps.
That is a document prepared by the FBI and it is not clear where the FBI person who wrote that got their information. They look like asphalt roadways. I note that BBN in its HSCA report stated that Elm St. was “about 40 feet wide” which sounds like they didn’t measure it. .
Sounds like a typo. The Hum-3D model has a width of 78.6". Without a 1961 Continental in front of me, I can't tell you what that 76.8" (if accurate) measurement refers to (the width of the rear bumper only?). If someone could, please let me know.
I can't travel back in time and set up laser scanners to give you a figure in inches. Would you agree that JFK's line-of-travel was not in the center of the middle lane, as you tried to con people into believing?
So let’s assume you are right and the lanes are 13’4” or 160 inches wide. If the lane makers are 4 inches wide then the middle is 78 inches right of the right edge of the left lane marker.
If the left edge of the car is 10 inches right of the right edge of the lane markers, then the right side of the car is 76.8” farther right or 86.8” left of the right edge of the left lane marker or 8.8 inches right of the centre of the lane.
So the question is: how far is JFK’s midline left of the car right side? I would suggest that JFK’s ribs were four inches left of the inside wall of the car and that the right edge of the car was a further 6 inches from that wall. If you add 8 inches from his ribs to his spine, this puts his midline 18 inches from the right edge of the car or 86.8-18=68.8” right of the lane marker and 9.2” left of the centre of the lane.
If the lanes are 12’ wide, the middle is 70 inches right of the right edge of the left lane marker, JFK would be 1.2 inches left of the centre.
So, yes, I admit that JFK is left of the centre line by 1.2 to 9.2 inches depending on the lane width. If the car is actually 78.6” wide as you suggest, then JFK’s midline would be between .6 inches right and 7.4 inches left of the midline.
I wasn't referring to the lampposts. What do you make of how far removed the rounded curb and north end of the reflecting pool are relative to the Itek Map? Are you going to continue to use that map?
All I need is a surveyed map with an accurate scale. I could agree to google maps if you can establish that there was no change in road width since 1963. According to Google maps the measured width is 11.8 m (38.7 feet).
