I would be curious to know what part of AP (the one that they are selling now, not EAP) you think would improve with HW3.
The part where it sometimes runs into things.

Autosteer and TACC are a part of EAP, FSD, and AP. There are at least a handful of documented incidents in which Autosteer/TACC have run into things.
The Model X that got into the accident on the 101 was surely not on AP1. Regardless, I believe there is far, far more improvement possible with Autosteer/TACC.
HW3 vehicles should be better even on regular AP or even non-AP safety functions if for no other reason than that they will have the computing power to run the NNs on full-scale images, instead of downscaling them to 1/4 the resolution (1/2 in each direction) before processing them. So they should do a better job of recognizing things, especially at a distance.
- Less/elimination of Phantom braking?
Local roads (not currently recommended, but also not disallowed)
.
Things that I suspect HW3 will do better vs HW2.5 while using AP:
- Identifying and maneuvers relative to non-car hazards (ie potholes, bikes, pedestrians, etc)
Wouldn't you agree that as Tesla starts to make NN enhancements towards FSD, that the quality of the vehicles awareness and actions even for general AP/EAP will increase too?
I just don't believe that the better hardware (full frame/ higher framerate/ etc) won't matter for AP/EAP.
The real problem is that they eventually will have 2 code bases. One for the hardware 2.5 computer and one for the 3.0 hardware. Eventually they will stop supporting 2.5 except for emergency safety repairs. I suspect that it will be very soon.
But that Model X also, besides using a much older version of the 2.x NN that has already seen a ton of improvement, crashed on an exit ramp
I think the lane centering is the strongest and weakest part about Tesla's Autosteer. Strong because it doesn't ping pong or drift (much) like other vendors implementations. Weak because it does lane centering to a fault and exposes the weakness of doing that when lane markings are not clear for exits/merges.Yes but I do not believe he was trying to take the exit, he was intending to stay in his own lane and so it was Autosteer and TACC that made the error here (not NOA). Autosteer still needs to recognize exits/medians to avoid crashing into them.
I last drove a 2.5 HW Tesla about a month ago, on the latest software, and it still regularly did the thing where it tried to stay in the middle of the lane no matter how wide the “lane” got. There were a few close calls with medians that made me nervous enough to take over. This was without NOA turned on, btw. So pure Autosteer/TACC.
Perhaps to make everyone happy they can let each driver decide if they want to use the new or the old NN on their HW3. In our minds. My car will be on the new NN and your car can be on the old one as per your preference. Everyone wins!
Since AP doesn't need all the cameras (since it only functions in a single lane) the 2.5 computer could already handle everything at full frame rate... (remember when EAP originally said it'd only use 4 cameras? That's because HW2.5 can handle 4 cameras no problem at full rate...and if the NN doesn't have to worry about lane keeping and TACC and changing lanes and taking exit ramps all at the same time, you don't ever need more than 4 cameras.
It's my understanding that AP2/2.5 only runs with reduced resolution, because that's how the NN is compiled. Plus, in theory, all those other cameras are always active for safety functionality anyways... (at least now that they're in use for them)
Safety functions still need "all" the cameras, and are always on, which means that probably everything is running at reduced resolution on HW2.x no matter whether you have (E)AP active or not.They run in reduced resolution because the 2.x computer is incapable of processing more than ~200 fps total... and 8 cameras times 30 fps is 240.
This wasn't an issue when they were only going to use 4 cameras for EAP as originally intended, since 4x30 is only 120.
But since they realized they'd need all 8 for things like NoA and enhanced summon to work so they had to go reduced resolution.
None of that matters for the new AP though since it doesn't do any of those things. New AP has no use whatsoever for anything but the front 2 cameras.
If you hit the turn signal it won't change lanes on its own, you need to break out of autosteer and do it yourself- but it can comfortably still handle the 2 side cameras on the side you have the turn signal on toward at full resolution for blind spot detection no problem.

Is this true though? My AP only vehicle (even with AP off) is constantly updating the screen with images of what cars are to the side/behind/coming up along side me. Wouldn't the computer be working to continually analyze all the cameras to determine what's there to display the info (even if it's not actually going to initiate a lane change)?
While theoretically possible, I doubt the screen GUI does anything other than leech off the data from what the vision system is seeingThe amount of info needed for "is there a car kinda somewhere around here so I can show it on the display" is vastly different from "I need to know precisely where every vehicle is because I'm going to automatically be piloting the car between them" (again remember the "all 8 cameras" thing only got enabled in V9, when Nav on AP became a thing- using only 4 was apparently plenty for all previous EAP features)
Moreover the amount of processing needed is vastly different since new-AP doesn't ever need to care if there's cars in nearby lanes nor ever have to make a single decision based on such info... (while EAP and especially FSD sure do).
blind-spot warning will care- but only about the cars in the lane you're trying to turn into, and it only needs to be paying close attention to 2 cameras for that.
