Got a 30-day FSD 12.3.3 free trial on my 2 year old Model Y. Strangely, my 2024 Model 3 which was supposed to have it 2 weeks ago (transfer) when I took delivery still doesn't have it. But that's another topic. So here are my conclusions after a 25-30 mile test drive to Sam's Club (closed) parking lot and back home on a Sunday afternoon:
POSITIVES
I do understand that 'everyone' is supposed to be getting this so Tesla is super-cautious. It's also an early 'all neural-net trained' version of FSD so... looking forward to getting FSD 13.x now? ).
If FSD 11.x behaves as a fresh, impulsive and insecure teenage driver, FSD 12.3.3 would be a healthy, super cautious, 90-95 year old.
POSITIVES
- definitely safe, unless you feel unsafe when everyone else on the road seems to be in more of a hurry than your car
- good 0-40 acceleration as the light at the intersection turns green
- no longer obeys 'speed' settings. Max speed is no longer the speed it attempts to achieve. It seems to be happy to stay at the posted speed limit - will maintain a posted speed limit if you are driving on an empty road - unless other cars in front of you or to your right/left move faster. I felt intense frustration while on FSD 12.3.3.
- lane changes take significantly longer to complete as the car appears to be more hesitant/less confident
- slammed on the brakes at a yellow light through which FSD 11.x would have passed without hesitation
- still missed moving into a long left turn lane (same as FSD 11.x) and it was 2 lanes to the right of that lane at the time it was supposed to change into turn lane
- was extremely confused (jerky maneuvers) at the large, 95% empty, Sam's Club parking lot
- no longer spells out on the screen the reasons behind its behavior, probably because of its mostly mindless 'neural net' training where it does things because other drivers do it but has no idea why it does it (is this really the future of AI?)
