Autosteer under the Autopilot option is lane-keeping on highways, it even specifies that in its definition.

Where?

"Assists in steering within a clearly marked lane, and uses traffic-aware cruise control"

Where is "highways only" defined? Even their new definitions aren't consistent.

And great... I have to dig through support pages to find it!

Which exactly 0 competitors do. Hyundai, Toyota, Volvo... every company page I look at makes it abundantly clear what comes on the product (on the sale page) without digging through support pages. You know what else they do? Specify the feature without calling it some "fancy" shit. Adaptive cruise control is called out as just that. Not renamed to "Traffic-Aware Cruise Control" and then hidden under "Autopilot" with a vague definition and only presented to you at the sale page under "Full Self-Driving".

Here's a snippet from the user manual of a Model 3 2022... (I've reformatted it a little bit... cause the raw copy-pasta was atrocious)

These Autopilot convenience features are designed to reduce driver workload:
Traffic-Aware Cruise Control (see Traffic- Aware Cruise Control on page 85)
Autosteer (see Autosteer on page 91)
Auto Lane Change (see Auto Lane Change on page 93)
Autopark (see Autopark on page 98)
Summon (see Summon on page 100)
Smart Summon (Smart Summon on page 103)
Navigate on Autopilot (see Navigate on Autopilot on page 95)
Stop Light and Stop Sign Warning (see Stop Light and Stop Sign Warning (U.S. only) on page 94

And another snippet from a model 3 2020 manual...

These Autopilot convenience features are designed to reduce driver workload:
• Traffic-Aware Cruise Control (see Traffic-Aware Cruise Control on page 111)
• Autosteer (see Autosteer on page 118)
• Auto Lane Change (see Auto Lane Change on page 120)
• Autopark (see Autopark on page 126)
• Summon (see Summon on page 132)
• Smart Summon (Smart Summon on page 132)
• Navigate on Autopilot (see Autopilot on page 123)

So is smart summon, Auto Lane change, Navigate on Autopilot, an FSD thing? Or an Autopilot thing? I thought that Autopilot was just super simple? I thought the features WERE NEVER included in autopilot definition... And yet YEARS of manuals for the damn product says you're wrong. And that their current definitions have been modified.

Autopilot according to Tesla's OWN manuals is the feature set that ALL other "smart" driving features fall under. Just like with plane-based autopilots funny enough. But you do you man. There's no changing your mind on this and you've made that clear long ago. I just hope that others see how absurd this all is.

Edit:

Basic Autopilot

Also would like to see where that definition is... Cause you used the term... but it doesn't exist anywhere else.

For Model X as well (and in NA in case you're going to say "other regions")... Check page 95 in the pdf... Weird that a 2019 Model X has all those features labeled as "Autopilot" too eh?

Edit3: Minor formatting issue.
