FSD V14.1.7 | Near Accident This is without a doubt the closest I have come to getting into an accident in a long time. I think had I not taken over and slammed on the brakes we would not have slowed down in time. You can see that FSD does an incredible job reacting to the car (even before I noticed it) and was slowing down, but it was not slowing down enough to stop in time. As soon as I saw the car swerving to the right I worried she was going to bounce back into my lane so that is when I decided to go full on the brakes to stop the car. You can see prior to me taking over we were full regen braking (which is FSD reacting well) but it wasn't using any real brakes at all, and ABS was not active until I took over. Let me know what you all think in the comments. I still think FSD is incredible - the reality is if you watch the video the car saw and reacted to the situation before I did, it just didn't brake as agressively as it needed to in this situation. FSD + an attentive driver is without a doubt in my mind still safer than a normal human driver who is not using FSD.

@karpathy In Los Angeles it's perfect on city streets, it's only on the freeways where it needs work. Worst offender is the 110 freeway toll roads. I use it every day and it's worth every penny even with my freeway frustration.

I took delivery of a beautiful new shiny HW4 Tesla Model X today, so I immediately took it out for an FSD test drive, a bit like I used to do almost daily for 5 years. Basically... I'm amazed - it drives really, really well, smooth, confident, noticeably better than what I'm used to on HW3 (my previous car) and eons ahead of the version I remember driving up highway 280 on my first day at Tesla ~9 years ago, where I had to intervene every time the road mildly curved or sloped. (note this is v13, my car hasn't been offered the latest v14 yet) On the highway, I felt like a passenger in some super high tech Maglev train pod - the car is locked in the center of the lane while I'm looking out from Model X's higher vantage point and its panoramic front window, listening to the (incredible) sound system, or chatting with Grok. On city streets, the car casually handled a number of tricky scenarios that I remember losing sleep over just a few years ago. It negotiated incoming cars in tight lanes, it gracefully went around construction and temporarily in-lane stationary cars, it correctly timed tricky left turns with incoming traffic from both sides, it gracefully gave way to the car that went out of order in the 4-way stop sign, it found a way to squeeze into a bumper to bumper traffic to make its turn, it overtook the bus that was loading passengers but still stopped for the stop sign that was blocked by the bus, and at the end of the route it circled around a parking lot, found a spot and... parked. Basically a flawless drive. For context, I'm used to going out for a brief test drive around the neighborhood to return with 20 clips of things that could be improved. It's new for me to do just that and exactly like I used to, but come back with nothing. Perfect drive, no notes. I expect there's still more work for the team in the long march of 9s, but it's just so cool to see that we're beyond finding issues on any individual ~1 hour drive around the neighborhood, you actually have to go to the fleet and mine them. Back then, I processed the incredible promise of vehicle autonomy at scale (in the fully scaleable, vision only, end-to-end Tesla way) only intellectually, but now it is possible to feel it intuitively too if you just go out for a drive. Wait, of course surround video stream at 60Hz processed by a fully dedicated "driving brain" neural net will work, and it will be so much better and safer than a human driver. Did anyone else think otherwise? I also watched @aelluswamy 's new ICCV25 talk last week (x.com/aelluswamy/sta…) that hints at some of the recent under the hood technical components driving this progress. Sensor streams (videos, maps, kinematics, audio, ...) over long contexts (e.g. ~30 seconds) go into a big neural net, steering/acceleration comes out, optionally with visualization auxiliary data. This is the dream of the complete Software 1.0 -> Software 2.0 re-write that scales fully with data streaming from millions of cars in the fleet and the compute capacity of your chip, not some engineer's clever new DoubleParkedCarHandler C++ abstraction with undefined test-time characteristics of memory and runtime. There's a lot more hints in the video on where things are going with the emerging "robotics+AI at scale stack". World reconstructors, world simulators "dreaming" dynamics, RL, all of these components general, foundational, neural net based, how the car is really just one kind of robot... are people getting this yet? Huge congrats to the team - you're building magic objects of the future, you rock! And I love my car <3.

@jpsilvashy @karpathy By worth nothing do you mean $0? Because I think you're just talking out of your hole.

@karpathy @jpsilvashy By the time they do that some will feel neglected to the point they move onto other brands.

@DennisCW_ What is it they have to protest Tesla about? They are upset about an American company having success because they don't like Elon?

🚨LOS ANGELES County: 900,000 Republicans have not voted yet. Dems are beating us BY 40 POINTS in LA. Unbelievable. How many homes do they need to burn down before you do something about it? Or do you expect @spencerpratt to do all the work? PULL YOUR WEIGHT
Elizabeth Barcohana@E_Barcohana

☀️It is the weekend before Election Day Nearly 6 Million people have voted in California (25% turnout); half are Dems Typically, we see the turnout graph do a hockey-stick 🏒 bump this weekend Will all those 🔴 voters who talk a big game about in person voting show up?
