FSD Beta 9.1 and Pure Vision Navigate on Autopilot drives from a Supercharger near SpaceX headquarters in Los Angeles to Best Buy in San Francisco, stopping at Kettleman City Supercharger along the way. There was only one short disengagement at the very end of the drive after arriving in San Francisco, so technically you could say it went from LA to San Francisco with zero disengagements and only had one little intervention parking lot to parking lot. Technically I may not have even had to disengage, but the car got stuck in a left turn lane due to too much traffic and started turning left, and I was a little startled and took over to be safe, then re-enabled after a few seconds. Overall, this shows that Pure Vision Autopilot is pretty impressive and capable of long distance drives with zero disengagements just like the previous version of navigate on autopilot, which I've also taken between LA and Silicon Valley in the past.
