Here’s the specific timestamp of the incident you mentioned in case you wanted to actually see it: youtu.be/aqsiWCLJ1ms?t=1190The car wanted to move through the intersection on a green left turn arrow.

This was a demo of a very early alpha release of FSD 12 (current public release 11.4.7) representing a completely new and more efficient method of utilizing the neural network for driving and has already been fixed. It is not released to anyone outside of a select few Tesla employees. Other than that it performed flawlessly for over 40 minutes in a live demo.
