Better than the previous, regarding FSD interventions, so far. However, on my 2020 MS LR+ HW3 w Intel Atom, the promised ASS doesn't work. It actually tells on the screen it doesn't. ("Not yet.") Neither does the vision-only monitoring, as there is no cabin camera in my car. So the update's amazing new features are totally useless for me.

2020 MX luda HW3, no Actually smart summon. Bummer 12.5.4 seems better than 12.5.2.1 but still way worse than 12.3.6. 12.3.6 seemed handle everything much better on HW3 at least.

FSD 12.5.4 is an improvement over 12.3.6, with a regression or two. Turns involved very jerky and startling corrections, over/understeering. With dumb summon, 2023 MYLR pulled into my garage but inconsistently. Sometimes pulled in 1' from the back wall, sometimes 2-3' short. Also, MYLR remembers garage door even after it's lifted; MYLR refuses to go further. The only Smart Summon improvement would be the ability to target a particular parking space to send it.

The update we've all been waiting for is here, however it's worth mentioning it has some odd quirks that I wasn't expecting. In the 2 days I've used it, it made 1 unsafe lane change which got me beeped at and it uses the wrong turning lane on my route home now. Aside from these issues, it's made me grin feeling like I have my own personal uber driver on-demand.

Seems pretty good although much more timid and less confident then 12.5.1.5. I'm back to hitting the accelerator to give it a push at stop signs and red lights whereas with 12.5.1.5 the second it stopped or light went green off we went. Why is it ALWAYS two steps forward, one step backwards with FSD. I've never seen development where everything they fix or add they break twice the amount. Overall still good but wishing I didn't update

Improved overall performance now that I have a pretty good handle on user interface. Stupid message continues when your right foot is resting on accelerator generating message: “Car will not brake in cruise control”. Interface continues to obfuscate information through mini dialogue boxes in the bottom lower left of screen. For some drivers seat height/steering wheel settings block display area.

ASS is phenomenal. Noticed some improvements and regressions pertaining to speed with FSD, so neutral on that front. Notably, the car will sometimes read speed limit changes and react to them, but will still show the old limit in the UI. Should be cosmetic, but this is odd.

So far no issues with FSD. I do notice that speed control is different. Hard to explain how. Also love me some ASS (Actually Smart Summon)
