Electrek about the NVIDIA platform. It seems that most car manufacturers are using it, with Tesla being the notable exception, as they already have their own FSD computer.

Mercedes, which just introduced Level 3 autonomous driving, uses the NVIDIA system, but it seems to be backed up by a lot of proprietary data and software. Personally, I think Mercedes’s approach to Level 3 is very smart. Unfortunately, it’s only found in a Mercedes S-class and EQS at this point.
It sounds like NVIDIA has a new chip called the Drive ORIN capable of 200+ trillion operations per second. I think this chip might be too new to be found in the Lucid but would be happy to be wrong. The prior version does about 30 trillion operations per second, while Tesla’s FSD does 144 trillion. Of course, the chip isn’t enough. Road data helps, and it’s unclear if NVIDIA will share accumulated road data amongst its clients. NVIDIA’s AI algorithms are open source though.
