Musk described gathering surround video from eight cameras operating simultaneously with synchronized frame rates.

Judge whether Tesla vehicles at the time (January 2021) had eight cameras that capture video at the same time with synchronized frame rates, used for surround video. TRUE: Tesla technical documentation or credible technical reporting shows eight cameras capturing simultaneously with synchronized frames. MOSTLY TRUE: there are eight simultaneous cameras, but a minor detail differs, for example the frame rates are only roughly synchronized or some models had a slightly different camera count. MIXED: the camera count is right but they do not capture simultaneously, or the reverse. MOSTLY FALSE: the number of cameras or the way they operate is materially different from the description. FALSE: Tesla vehicles did not have an eight-camera system that captured at the same time.

Set before the research began.

   “The sensor package designed into Tesla Model 3 includes: eight cameras which provide 360-degree visibility around the car within a radius of 250 meters; 12 ultrasonic sensors that complete this vision system.”

   “Tesla vehicles with Hardware Suite 2.0+ (Model 3/Y since the first production, Model S/X produced after August 2017) create the car’s 360° vision with the help of 8 cameras (3 in the front, 2 on the side repeaters, 2 in both the B-pillars and one rear-view camera)”

    “For example, if they want to fuse with 2 seconds, and given that the cameras work at 36 Frame Per Second, N would be 72.”

    “The 8 cameras on a Tesla are 1280 x 960 12-Bit (HDR) @ 36Hz.”

Several independent sources say Tesla vehicles with HW2 and later had eight cameras giving 360° coverage (E1, E5, E6, E9), and E3 lists where they sit. An independent technical blog explaining Tesla's vision system says the eight images are all synchronized and fused through a shared backbone (E8). Two sources give a common camera rate of 36 Hz (E10, E11). E7 describes how the software used the cameras in 2017, not how they captured video in 2021, so it does not contradict the claim. The evidence for synchronization is thinner than the evidence for the camera count: one source says the eight images are all synchronized and fused [E8], and others say the cameras work at 36 frames per second [E10, E11], but none directly describes the timing of capture.
