You're right that it's not proof of anything, and I could also post the front-facing camera, but ultimately I was just showing an example of the numerous times FSD crossed lane lines. It could be me driving, but it's not, and you're welcome to take that at face value or not. Skepticism on the internet is healthy, and I appreciate yours.
FWIW the visualization in-car shows the lines, and the vehicle crossing them, clearly in each of these situations which include driving in a straight line between clearly marked lanes.
I do plan on speaking to Tesla about it at my next service appointment, but I just figured FSD was hyped up like Summon. Still pretty cool as a driver assist function, but based on the amount of times it wanted to swerve me out of my lane into cars typically on the left side of me I've quit using it while other vehicles are around.
