Tesla has deployed FSD v15 early build to its Robotaxi fleet across six US cities, with 380,000+ miles accumulated and a safety record. The system is 40% complete with a tenfold parameter increase; full rollout expected late 2026 or early 2027, and FSD v15 will be exclusive to Hardware 4 vehicles, effectively orphaning older Hardware 3 users.

This Wire brief sits within Fusion42's coverage of Autonomous Vehicles. Wire is Fusion42's founder-focused intelligence feed: each story is connected to the funds and startups it names — every one with a live profile on Raise or Scout — so founders can follow the capital and the momentum behind the headline rather than just the headline itself. Wire analysis is one of the live surfaces Arthur reasons over.

◆ The Wire takeaway

Tesla just locked FSD v15 to Hardware 4 only, killing support for Hardware 3 forever. If you're building sensors, compute modules, or fleet management software for autonomous vehicles, you now know the hardware generation your customers will be forced to upgrade—and when.
