Questions & Answers

Q: How does Tesla improve the efficiency of their compute in self-driving cars?

Tesla puts effort into optimizing their compute for maximum efficiency, creating their own C compiler. They have dedicated software engineers working at a bare metal level to improve efficiency and use of the trip accelerators, ultimately achieving high frame rates and low latency.

Q: What is the advantage of removing post-processing on the image in Tesla's self-driving cars?

By removing post-processing, Tesla can obtain raw photon counts and capture more data, even in low light conditions. Additionally, they save 13 milliseconds of latency by bypassing the image processor, which is crucial for real-time decision-making in self-driving cars.

Q: How does Tesla handle latency and jitter in the self-driving car's control systems?

Tesla tracks latency and jitter throughout the entire pipeline, from photon hits to output commands. They aim to reduce latency by updating the drivers on steering and braking control to have a higher frequency. Jitter, which can cause variable latency, is a challenge that requires interpolation to make robust control decisions.

Q: How does Tesla aim to surpass human maneuvering abilities with Full Self-Driving?

Tesla believes that over time, their Full Self-Driving system will be capable of maneuvers far beyond human capabilities. They envision the cars maneuvering with superhuman ability and reaction times, surpassing even the impossible maneuvers seen in action movies.
