Reddit user adds AMD GPU to Toyota to run openpilot; comma.ai faces NHTSA probe
A Reddit user fitted an AMD Radeon RX 9060 graphics card into a 2021 Toyota Alphard so comma.ai's open-source openpilot could run an end-to-end model locally and drive hands-off on the highway; the post claims 21.4 TFLOPS of FP32 compute, an ~880M-parameter model called Chestnut and performance on par with Tesla's HW4, none of which has been independently verified. Separately, the U.S. NHTSA opened an investigation last month into comma.ai's aftermarket driver-assistance hardware — comma three, 3X and comma four — and the openpilot software, covering roughly 30,000 vehicles, with public records citing five serious highway collisions that killed three people and injured 11. Founded by George Hotz, comma.ai open-sourced openpilot in 2016 under regulatory pressure and has shipped just over 30,000 units in total.
It shows how open-source aftermarket driver assistance strains against compute, driver-monitoring and liability limits as regulators step in.
最近 Reddit 上的一条帖子火出圈了，有位老哥给他的老款丰田插上了一张 AMD 显卡，实现了可以脱手的辅助驾驶。
画面里是一辆在高速公路上自主行驶的 2021 款丰田埃尔法，仪表台的正中间，插着一张 AMD Radeon RX 9060，配套的线束交织在一起，顺着中控台向下延伸。
苏妈看了都得愣半天。
插上了显卡，这辆埃尔法就像是打了超级战士血清的美国队长，被蜘蛛咬了的彼得·帕克，暴露在伽马射线里的绿巨人，突然就拥有了高达 21.4 TFLOPS 的单精度浮点算力（FP32），FLOPs 直接拉高了 100 倍。
