Tesla FSD 2025 Updates: 10x, School Bus Test & 2025.2.8

Tesla FSD 10x Parameter Update: What It Means

The "10x parameter update" refers to a Tesla AI and FSD development milestone that generated significant community discussion in 2025. Elon Musk and Tesla's AI team indicated they were deploying a neural network with 10x the parameters of the previous FSD model.

What "parameters" means in AI

Parameters in AI ≈ connections in a neural network. More parameters = more capacity to learn complex scenarios. The 10x jump moves FSD into the range of large language model territory — hundreds of billions of parameters.

Tesla's FSD v13 and v14 showed marked real-world improvement in city driving, unprotected left turns, and complex intersection handling — improvements attributed in part to this neural scaling approach.

What Changed for Owners After the 10x Update

Owner Improvements Reported

✓Fewer disengagements in complex urban environments
✓More confident handling of school zones, construction areas, unusual lane configurations
✓Improved behavior around cyclists and pedestrians in ambiguous situations
✓Smoother speed profile (less "phantom braking")

Tesla FSD School Bus Test: The Milestone

"Tesla fsd school bus test" refers to Tesla's public demonstrations and owner-reported experiences of FSD navigating past school buses — one of the most legally and ethically significant edge cases in autonomous driving.

US law in all 50 states requires vehicles to stop when a school bus has its stop arm extended and flashing lights active. Tesla's FSD system has demonstrated correct school bus stop behavior in widely shared owner videos and internal Tesla testing.

This does not mean FSD is infallible in all school bus scenarios — corner cases remain edge cases where driver attention is required.

Tesla Software Update 2025.2.8: Status and What's in It

Software version 2025.2.8 was one of the Tesla over-the-air updates that generated significant community tracking in early 2025.

What 2025.2.8 Contained

FSD behavior refinements (improved handling of traffic cones and temporary signage)
Navigation improvements for multi-stop routing
Bug fixes for the Grok voice assistant integration
Charging curve optimization for certain battery configurations
Various UI stability improvements for the center display

Why Some Vehicles Get Updates Later

Tesla staggers rollouts to catch software issues at small scale before fleet-wide deployment. There is no publicly documented criteria for which vehicles receive updates first — it appears to be randomized by VIN range with some geographic clustering. It's not based on subscription tier or account level.
