FSD x ASS

TShieldsESQ | 2026-01-27 14:50 | 22 views

I’m amazed at the performance gap between FSD and ASS. I use FSD hundreds of miles a week in cities, highways, parking garages, etc. ASS struggles to navigate through a mostly empty parking lot.

Yeah I used ass a few times and it was cool but way too embarrassing.

I have tried it a few times just for the novelty of it and it was very disappointing

They are two different software stacks. Presumably it’ll get phased out and replaced with just the one FSD stack as v14 is being trained on parking lots so there won’t be a need for a separate software stack once they are comfortable with letting v14 handle summon.

Possibly 14.3.

That makes sense

ASS is a different stack that prioritizes safety over speed. FSD expects you in the car to intervene more easily so it favors speed. They aren't the same thing at all.

We need better acronyms.

My worry is this won’t happen because you only need premium to use summon but you need to subscribe or buy FSD to access the software. I have a feeling they don’t want people to be able to use any part of FSD without paying the price for it. Either that, or the things summon needs to do simply isn’t possible with FSD (telling it to stop at an exact point based on your distance) for whatever reason. Really REALLY hoping I’m wrong on both fronts.

What do you mean you need premium for summon? You need FSD for that right?

You need FSD for summon.

Forgot about enhanced since it hasn't been offered for a long time.

i just got the car and its kind of a hodge podge of options. Been trying out the Autopilot menu and none of it is impressive. Dunno if FSD is better, but my car needs a hardware upgrade for 1k to even try it out, apparently.

Yea it's so bad I can't remember the last time I used it. I believe it's a completely different software than FSD? One of the primary benefits with v14 was improved parking lot performance so I'm assuming the idea is to consolidate the stack? In other words, once unsupervised, there won't really be a need for ASS to be a separate "feature"
