Tesla Full Self-Driving v14.2.2.5 Review: Mixed Improvements & Strange Behaviors (2026)

The Evolution of Tesla’s Full Self-Driving: A User’s Perspective

Have you ever wondered what it’s like to live with a car that’s constantly learning and evolving? Tesla’s Full Self-Driving (FSD) system is a prime example of this, and as someone who’s been using it for years, I can tell you it’s both fascinating and frustrating. The latest update, v14.2.2.5, has been a rollercoaster of surprises, and I’m here to share my thoughts on what works, what doesn’t, and what it all means for the future of autonomous driving.

The Good, the Bad, and the Confusing

Let’s start with the speed profiles. Tesla’s FSD has always been a bit of a wildcard when it comes to speed, but this update feels like a mixed bag. On one hand, I’ve noticed more consistency in how the car behaves in different driving modes—Standard, Hurry, Chill, and Mad Max. For instance, Mad Max no longer crawls under the speed limit like it did in previous versions, which is a welcome change. But here’s the kicker: what’s ‘just right’ for one driver might feel too fast or too slow for another. Personally, I’d love to see Tesla find a middle ground that satisfies most users without feeling like a compromise.

What makes this particularly interesting is how subjective driving preferences are. Tesla’s challenge isn’t just about coding the perfect algorithm; it’s about understanding human behavior and expectations. In my opinion, they’re getting closer, but there’s still room for improvement.

The Turn Signal Enigma

Now, let’s talk about something that’s left me scratching my head: the turn signal behavior. Imagine this—you’re taking a sharp turn on a road, and the car decides to signal as if it’s changing lanes, even though you’re staying on the same path. Or worse, it ignores the navigation and signals in the opposite direction of where you’re supposed to go. This has happened to me multiple times with v14.2.2.5, and it’s not just annoying—it’s confusing.

One thing that stands out here is the disconnect between what the car thinks is ‘normal’ and what actual human drivers would do. I’ve seen Tesla fans argue that signaling on a sharp turn is a valid driving practice, but let’s be real—nobody does that unless they’re turning into a driveway or changing lanes. It’s a minor issue, sure, but it’s also a reminder that FSD still has a long way to go in mimicking human intuition.

Parking: The Never-Ending Struggle

Parking has always been FSD’s Achilles’ heel, and unfortunately, this update hasn’t changed much. I’ve had the car attempt to park in spots partially covered in snow or blocked by abandoned shopping carts. Both times, I had to intervene manually. What’s even more baffling is that when I choose the spot myself, the parking performance is significantly better. It’s almost as if the car struggles with decision-making when it comes to selecting a parking spot.

What many people don’t realize is that parking isn’t just about maneuvering into a space—it’s about understanding the environment. A pile of snow or a stray cart might seem like minor obstacles to a human, but for an AI, they’re complex variables that require better contextual awareness.

The Surprising Improvements

Despite the quirks, there are moments when FSD shines. For the first time, my Tesla slowed down in a school zone, matching the speed of other cars rather than strictly adhering to the posted limit. It’s a small detail, but it shows that the system is learning to adapt to real-world scenarios. Even more impressive was when it spotted a deer by the roadside and slowed down to avoid it. These are the moments that give me hope for the future of autonomous driving.

In my opinion, these instances highlight the potential of FSD when it’s allowed to learn from real-world data. The challenge for Tesla is to make these behaviors consistent rather than one-off successes.

Navigation: The Persistent Headache

If there’s one area where FSD still falls short, it’s navigation. I live in a neighborhood with a right-turn-only exit, but FSD insists on trying to take a left turn every time I leave. It’s a simple route, yet the system can’t seem to figure it out. And don’t get me started on the baffling routes it sometimes chooses for straightforward trips. Navigation is the one thing I desperately want Tesla to fix, but so far, it’s been a stubborn problem.

What makes this particularly frustrating is that navigation is the backbone of any autonomous driving system. Without reliable routing, even the most advanced driving capabilities feel incomplete. Tesla needs to prioritize this if they want FSD to truly live up to its name.

Final Thoughts

Tesla’s FSD v14.2.2.5 is a testament to how far autonomous driving has come—and how far it still has to go. It’s a system that’s constantly evolving, with moments of brilliance overshadowed by frustrating quirks. As a user, I’m both excited and impatient. Excited because I can see the potential, and impatient because I want that potential to be realized sooner rather than later.

One thing that stands out here is the delicate balance between innovation and reliability. Tesla is pushing the boundaries of what’s possible, but they also need to ensure that the basics are rock solid. In the end, it’s not just about creating a self-driving car—it’s about creating one that people can trust.

So, here’s my takeaway: FSD is a work in progress, but it’s a progress worth watching. If Tesla can iron out the kinks and focus on consistency, they might just redefine the future of driving. Until then, I’ll be here, sharing my experiences and hoping for the best.
