V1.2 of @CamCutApp is out now! All the beautiful chilren can now enjoy 🇺🇸 USA Flag Road, Rainbow Road, Matrix Rain Road, and any custom color scheme you can come up with.
I’m probably going to spam you with USA Flag Road because I love this country so much 🇺🇸 🫡
The crash analysis below shows AI3 FSD v12.6.4 biggest safety weakness: late reaction.
This video uses official dashcam crash footage synchronized with the vehicle’s official telemetry logs obtained from Tesla and visualized in @CamCutApp.
The telemetry shows FSD waiting about 0.67 seconds after the lead vehicle’s brake lights illuminate before it begins braking. From the moment the lead vehicle starts braking until Automatic Emergency Braking intervenes is about 1.5 seconds. During that time, the Tesla slows by only 4 mph, from 62 mph to 58 mph.
By the time AEB takes over, only 132 feet remain before impact. There simply isn’t enough distance left to avoid the collision.
Millions of AI3 vehicles are still running FSD v12.x. Situations like this require the driver to intervene before it becomes obvious that FSD isn’t braking quickly and aggressively enough, and that’s not always easy to judge in real time.
Tesla today announced AI3 v14 Lite which includes “significantly improved safety.” When I get a chance to evaluate v14 Lite, this is exactly what I’ll be testing first. In my opinion, it’s the most important and critical improvement the system needs.
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.
This build distills the driving behavior from AI4’s v14 series into both the camera and compute config of AI3. It includes destination options and speed profiles on city roads, but more importantly significantly improved safety.
We hope you’ll enjoy it, once the build ships wide.
