Tesla’s Full Self-Driving suite, now at version 13.2.9, is the company’s latest stab at making cars that drive themselves without you sweating bullets in the driver’s seat. It’s still “Supervised” FSD, meaning you’ve gotta keep your hands on the wheel and eyes on the road, but the system is doing the heavy lifting—steering, braking, accelerating, and making decisions that’d make a human driver’s head spin.
So, how’s it pulling this off? FSD 13.2.9 is powered by Tesla’s neural network, running on the company’s custom Hardware 3 (and newer Hardware 4) chips. Unlike older versions that leaned on hardcoded rules, this iteration is all about end-to-end machine learning. It’s like the car’s brain is binge-watching millions of driving scenarios, learning to predict and react in real time. The system uses a dozen cameras (no radar or LIDAR, because Elon Musk says vision is king), feeding 360-degree visuals into the neural net to map the world, spot obstacles, and plan paths.

The Hollywood Hills are no joke. Narrow roads, sharp turns, and driveways that spit cars out like surprise party guests. In the video, the Tesla glides through this like it’s auditioning for a Fast & Furious cameo. FSD 13.2.9’s trick here is its improved spatial awareness. The neural net doesn’t just see the road; it understands the context—curbs, parked cars, oncoming traffic, even the vibe of a residential street. It’s predicting where that delivery van might pull out or if a pedestrian’s about to jaywalk. The car’s path planning is silky, hugging curves without jerking the wheel, and it’s making decisions faster than you can say “cut to commercial.”
Then comes the real test: Downtown LA at rush hour. If you’ve ever driven there, you know it’s a gladiatorial arena—cars weaving, pedestrians ignoring crosswalks, and traffic lights that feel like suggestions. The video shows the Tesla merging onto freeways, dodging aggressive drivers, and navigating stop-and-go traffic without breaking a sweat. This is where FSD 13.2.9 flexes its urban chops.
The secret sauce? Tesla’s “vector space” modeling. Instead of just seeing objects, the system builds a 3D map of everything—cars, bikes, traffic signals, even construction cones—and predicts their trajectories. It’s like the car’s playing 4D chess while you’re just trying to pick a podcast.
In the clip, it handles lane changes with human-like finesse, signaling early and sliding into gaps without cutting anyone off. It even anticipates traffic light changes, slowing down smoothly instead of slamming the brakes. This most certainly is proof that FSD is inching toward “Unsupervised” territory, where you might actually kick back and let the car do everything.
