So I just picked up my car and will be using FSD 13.2.8 for the first time. I figured it was as good of a time as any to actually track how many KMs before I had what I considered to be a critical disengagement. I would count this... show more

Some of the replies on here are wild... I feel like I need to start driving around with the 360 camera on the roof in order to give more context. I would have thought 2 video angles would have been good enough, but apparently I am an idiot for disengaging and our almight FSD was making the appropriate decision, how foolish of me. 🙄 Just to package it all up in one reply, the road I was turning on has TWO lanes - FSD was trying to turn into the right lane. I saw the white car moving from the left lane into the right lane and FSD was still trying to turn into that lane. Had I not stopped that white car would have rear ended me 10000%. Photos to hopefully clear things up. ALSO JUST TO BE CRYSTAL CLEAR - I think FSD is incredible, there's nothing like it in North America. I praise it daily - but it is NOT perfect and sharing it's current limitations and issues is important. It helps keep people safe and hopefully lets @Tesla_AI see things that need to be worked on.

This isn't FSD problem, it's your problem. FSD will go if it's lane is available, not when the road is free. and I can see that in both of your disengagement!

This is most certainly an FSD problem... the lane wasn't available, there's a car merging into it. I saw that as a human, and had there been an accident I would have been at fault.

Mine has done this before almost in the exact same situation and right before i was about to press the brake it stopped and it was just creeping. Not sure if this was a similar situation or not lol

It may have stopped, but the 'tentacle' looked it like wanted to go onto the road... plus it just felt very uncomfortable. There's zero reason for the car to creep that agressively when there's traffic coming in the lane.

I see your lack of understanding what FSD (Supervised) will and won't do is main issue. Like in the real world, one's first time driving a car doesn't determine whether the car is safe or not.

My lack of understanding? I would argue I have used FSD more than 90% of people. I make content related to FSD and care a lot about the software. Tracking disengagements like this is important, it allows people to understand the real world safety of the car while using FSD.

That's nuts, I'm calling BS. Never had this one time since the v13 update. Never touch the wheel once, drive for hours in California. The car drives better then me I completely trust the system. Only time I disengage is because I change my mind & want to go a different way

Calling BS? Do you think this is an elaborate multi-cam AI fake video or something? FSD was moving forward into a lane that a car was driving in (70+KM/H).

That was clearly a Safety Related Disengagement -- the car on the left was changing lanes at the exact time the FSD Path Planner was moving your car into that lane. You would probably have gotten rear-ended. See the screen shot below.

I just dont understand why the car wouldn't back-off on its decision. I was saying "I wouldn't go" for more than enough time, the vehicle which is capable of making decisions MUCH faster than me should have saw that car and stopped.
