He argued that camera-only systems can reach a certain level of results early but struggle to move from 99.9% to 99.99%, and that driving ten times as many kilometers does not add the extra nines. Waymo is developing its own Sensor Fusion Processor.","whyItMatters":"Waymo's own framing is that more miles and more cameras do not buy the last decimal places, which is the argument behind building a Sensor Fusion Processor rather than following Tesla's camera-only route.","webCardHtml":"\u003cp\u003eRosenband\u0026#39;s keynote was not a walkthrough of the Sensor Fusion Processor itself. It was the case for why Waymo started building one. His example was a red balloon floating in front of a traffic signal, mistaken for a red light, and he noted that even Gemini still seems unable to judge correctly whether it is a signal or a balloon.\u003c/p\u003e\u003cp\u003eWaymo\u0026#39;s figures to 2020: more than 200 million miles driven, more than 20 million paid rides, 15 cities.

That is why the company is building its own Sensor Fusion Processor: the 99.9% to 99.99% gap is a hardware problem, not a data problem.","twitterPost":"Waymo's Daniel Rosenband: more kilometers don't add nines. The 99.9% to 99.99% gap is why Waymo is building its own Sensor Fusion Processor.","threadsPost":"Waymo's Daniel Rosenband told Hot Chips that camera-only systems plateau at 99.9% because driving ten times as many kilometers does not add the extra nines. Waymo's answer is a Sensor Fusion Processor of its own design, which puts the remaining gap in silicon rather than in more footage.","newsletterBlurb":"Waymo compute lead Daniel Rosenband used a Hot Chips keynote to explain why the company rejects a camera-only sensor set. His argument: early results come easily, but the last decimal places do not, and more driving does not add them.
