AUTO LANE CHANGE ISSUES CONTINUE W/ FSD V14.2.1.25 Starting with FSD v14.2, there has been a significant regression in the system's confidence when performing automatic lane changes. If a vehicle is following in the adjacent lane at a safe distance and consistent speed, the ego car will often activate...

🚨 One thing that has frustrated me with Tesla Full Self-Driving is that I find it will sometimes change lanes to overtake a car, but the lane it changes into either ends or goes against the navigation (for example, it will change into a straight lane when it needs to be in a turn lane) Inevitably, it has to get back over before the lane ends or to get into the correct lane, and it ends up in the same place it was initially. A good example:

This traffic circle has been a long-standing pain point for me on FSD. As you can see, the car consistently drives in the bike lane here. I’ve documented this behavior before on FSD 12, 13, and now 14. The issue appears to stem from outdated map data. This section of the circle used to function as a two-way roadway. At the time, there was no bike lane and vehicles traveled in the space FSD still prefers today. Since the redesign, that area is now a dedicated bike lane, but FSD doesn’t reliably recognize the change. Depending on the version, it will occasionally handle this correctly, but most of the time it does not. This is currently the only issue I consistently experience with FSD. It’s not safety critical. The car will move if a cyclist, vehicle, or object is present, but reliance on outdated map data in locations like this needs to improve.

Tesla FSD avoids a stopped car on the highway, then avoids a moving car in the adjacent lane when swerving. Impressive.

Tesla’s FSD has become really good at day-to-day driving, and it’s now performing like a human in very complex scenarios. Here’s video from last Friday, during afternoon rush hour. There’s a broken down pickup truck in the middle of the three open lanes in the Ville-Marie tunnel. Lights indicate that lane is closed. My car is in the leftmost lane, which suddenly also comes to a standstill, after police show up and an officer exits his vehicle and stops traffic. When it appears that the left lane will not start moving again, FSD moves my car two lanes over the right. 🤯 It then curves around a pothole in that lane, following how the car ahead handled it. 🤯 Honestly if it wasn’t for how bad Montreal roads are with potholes, I would hardly be driving myself at all.

A recurring frustration with FSD 14.3.3 It still doesn’t remember previous behavior on roads I drive every day. In both of these clips, the car unnecessarily jumps into the left lane (Hurry mode) despite clear reasons not to: • Video 1: The lane is ending and blocked by construction barrels. • Video 2: The left lane is becoming a left-turn only. In both cases, it had to force its way back into the right lane with traffic all around. Definitely not ideal.

With FSD v14.2.1.25, Hurry Mode is now perfect. Speed control is excellent, improved lane discipline (no left lane camping) and on the highway, there is no +10 cap anymore so it stays with the flow of traffic very well. So good.

FSD v14.2.1 + WINTER CONDITIONS UPDATE With yet another winter storm bearing down on the Upper Midwest, I wanted to remind everyone to stay vigilant when using FSD v14.2.1, especially in snowy conditions. While this build performs far better than any previous FSD version in winter weather (thank you Tesla AI for all the hard work!), there's a notable issue when transitioning from clear pavement to partially snow-covered surfaces—particularly during automatic lane changes at speeds >40mph. Once the lane change begins, the car starts swerving side-to-side, and the longer it continues, the more pronounced the hunting behavior becomes as it searches for drivable space. Earlier this week, I encountered this a few times during a mild snowstorm. With a lifetime of winter driving experience here in Minnesota, I decided to observe how far it would go. I was surprised that the system didn't disengage on its own, as it eventually put the car into a full slide toward the barrier, requiring my intervention. If you notice this behavior, I strongly recommend disengaging early and completing the lane change manually before re-engaging the system.

As requested, here is the footage. FSD 14.1.4 was taking a right out of a parking lot. There was a mail truck in the closest lane and FSD attempted to take a really wide turn around the truck and go into the far lane, but there was a minivan clearly coming in that lane. I wasn't sure which lane it was trying to get in. When it started going in front of the minivan I took over. The minivan was paying attention and braked, honked their horn, and went around me as I pulled out of their lane. I found it weird because 14 is usually way too cautious at intersections.

V14.2.1 highway regression vs 14.1. In standard mode, FSD makes a maneuver into the left lane to pass a semi truck. Because they have jailed the speed limits of non mad max profiles, FSD cannot use acceleration to make this pass. So it ends up camping the left lane. In my right side view mirror, you can see someone coming up on my ass, and FSD is not getting back over. It’s also not speeding up to pass the semi because it is in speed jail. I had to scroll mad max to get through the maneuver. Def a regression from 14.1.

Just took my Tesla Cybertruck out with FSD Supervised v13.2.9, and it’s next-level! 🤖 The end-to-end driving network is so smooth – nailed lane changes and handled a tight two-lane road like a pro. The 36 Hz AI4 video inputs and low latency make it feel like the truck’s reading the road in real-time.

A Kenyan driver has complained that along the Thika overpass leading into Thika, there is no lane discipline, with motorists doing as they please and harassing drivers heading in the opposite direction. He says drivers often turn the road into a four-lane highway, making it impossible to navigate.

Here’s Tesla Europe, Middle East & Africa FSD taking on the worst Dutch car city: Hilversum. Had 2 semi interventions: didn’t disengage but had to make it go manually: 1. Nav was pointing straight but the car chose a right-only lane, forced a lane change indicator and gas and it readjusted 2. Roundabout w split lane failed: was supposed to go straight but hugged a right only lane, used gas manually and it readjusted 3. Small issue: It parked perfectly into a tight space but didn’t fully go into the stall It also seems to ignore the “I have right of way” when it comes to bicycles that have a clear yield sign. This makes sense for safety. I’m biased because I’ve been driving FSD for 7 years in the US. For people who have this as their first experience - minds will be blown. This is absolutely next level and all European car brands will suddenly realize how far behind they are. The future is autonomous and I can’t wait until this rolls out EU wide.

This is what a very capable robotaxi looks like. First, FSD 14.3.2 notices the stopped bus blocking the lane, so it signals far in advance and moves over. Then, as we get closer, the bus starts pulling out, and FSD quickly anticipates that it will encroach into our lane, so it safely brakes to let it in. Smooth operator.

Watch this Tesla FSD v13.2.9 drive on the wrong side of the road as it attempts to use the oncoming lane as a turn lane, forcing the driver to disengage. @ElonMusk’s defective software should be banned from public roads.

Finally caught this low visibility, one-lane covered bridge during a complicated moment. How does FSD handle it? Like a legend. As we approach, FSD yields for the pedestrian and oncoming car. Before proceeding, FSD notices the approaching pickup truck, yields until it is apparent that the truck is going to yield for us, at which point it proceeds through the bridge flawlessly. FSD V14.2 demonstrates awareness of one lane bridge, understands that approaching pickup is a potential obstruction, and waits until it is clear that we can proceed. You can completely forget about this happening on any version pre-14. V14 does an incredible job with context and predicting potential future events. And it does it all so quickly and with such certainty. The intelligence is getting nutty.
