Sure, but there's two issues here. The turn signal is on in the other direction. Activation of the turn signal in base autosteer will disable autosteer. Activation of the turn signal in more advanced modes (Nav on Autopilot) will result in a lane change in the direction of the signal. There might be a way to trigger a scenario like this in an FSD equipped car with all FSD related features turned off, and a really careful sequence of events with the turn signal, I guess? I'd have to try it to be sure, but I think it'd actually take some work to do. But that last part does have me thinking it might be possible. The weird slowdown that he reported at the end could be consistent with AP finally giving up on alerting the driver and trying to "make safe" by slowing aggressively and probably going crazy with audible alerts. Maybe then the driver perked up and took off the ramp? But tbh, it all reminds me of a driver that I ran into (thankfully not literally) a while back. They were in an older car, so obviously not on ADAS... just driving that badly and probably under the influence. It happens a lot.
