Well-known FSD Beta tester Chuck Cook spotted a Tesla Model Y testing FSD V12 yesterday. The car was making rounds of the test loop where he usually drives his Tesla Model 3 on FSD Beta for testing the system and sending feedback to Tesa.
Chuck’s test loop is located in Jacksonville (JAX), Florida — and has a complex unprotected left turn (UPL). Tesla has officially named such difficult UPLs as “Chuck Cook style” in the Release Notes of FSD Beta 10.13.
The Chuck Cook UPL has been a tough challenge for the Tesla Autopilot team. Chuck and Tesla’s engineers have been training Autopilot FSD Beta on this left turn for more than a year now. He also met with Tesla Autopilot engineers at AI Day 2022 to discuss the performance of FSD Beta on this and such UPLs.
But the variable light to medium and heavy traffic plus other vehicles intersecting from the front make this turn a tough challenge for Tesla Autopilot.
A Tesla Model Y with a manufacturer license plate from Texas ticked Chuck’s curiosity. According to him, these testing vehicles have been in JAX for almost this entire week. Yesterday he decided to record the activities of Tesla’s official Model Y at this UPL which looked like an FSD V12 testing and evaluation (video below).
According to Chuck, he last saw official Tesla vehicles testing FSD Beta 10.6.9 earlier this year in the spring season. Chuck explains the difficulty of this UPL as follows:
It’s a very difficult turn for those of you who are not familiar with it. It’s a 3-lane divided highway with a median. Speed limit is around 50 miles an hour (mph) and the cars can go much faster than that, which makes the gap selection the most difficult part for crossing this road in positioning yourself in the median to continue on the 2nd part.
Although Chuck did not talk to the Autopilot testing driver in this instance, the way this Tesla Model Y halts at the stop line strongly suggests Tesla Full Self-Driving behavior. Since Chuck is testing the software for a long time now, he can easily differentiate between the creep behavior of human vs. Autopilot drivers.
According to Chuck Cook, the creep stance and behavior of the Tesla Model Y closely resembles to that in FSD Beta version 11.4.7.2.
FSD Beta 11.4.7.2 is the latest version that Tesla has rolled out for non-employee testers. FSD V12 is exclusively being tested by select Tesla employees before it goes out to Tesla vehicle owners outside the company.
Autopilot FSD 12 is the non-beta version of Tesla’s Full Self-Driving software. As soon as the beta testing program is concluded, Tesla will release this update to Tesla owners who have bought the $12,000 Full Self-Driving Capability package.
Tesla CEO Elon Musk demonstrated FSD 12 in a ~42-min live-stream video on X (Twitter) in August. His personal Tesla Model S has FSD V12 installed on it and he revealed during the demo drive that drivers around the world are testing it every day.
So, what we can see in the following video by Chuck Cook, FSD 12 in its several attempts, took the Chuck Cook’s UPL very precisely. Tesla engineers and staff has been testing and perfecting it for about a week at this location, training the Tesla AI neural net how to handle complex situations like this. Let’s watch!
