Why would I only go to 4.21.3 from4.18.10 when there are about 10 more upgrades out for my model and configuration car? Not to mention, 4.21.3 is adding the lane departure, smart summon, etc, which the update I'm on already has. 2 other main changes that I am not getting are the update with skyforce reloaded and all of the small update tweaks that come with that package, or even the latest update with disney plus... why wouldn't they just move me to a current one?

From 2021.4.18.10 to 2021.4.21.3 WHY?

Because it appears the path to the latest update is via 21.3 to 12.25.7 to 24.2. For whatever reason, there is no path directly from 18.10 to 12.25.7. 12.25.7 adds features which 24.2 doesn't have, so you have to get that update before you get 24.2. You (and I) will more than likely get the 12.25.7 update in the next few days, and then get 24.2 shortly after that. If you were on 18.10, then you have a vision only car like me. The various software versions worked to merge the radar cars with the vision cars. The ultimate end result should be the majority of the fleet being on 24.2 in the next few weeks.

I’m on 2021.4.18.11 (RADAR) and just got 2021.12.25.7. I was starting to wonder how and if I would get back to hanging out with the cool kids at the front of the line.
Before my last update I was always one of the early ones, but between then and now I’ve been sitting on the sidelines watching.

Strongly doubt that. The 2021.1.21.3 is a completely different branch for some selected number of cars. It came from the allegedly testing branch for the new neuro nets, following a different path from the mainline releases and has about 10% of the cars at least per Tesla-Fi statistics
As far as I remember, it went like this is recent history
separate branch(testing something maybe, development?)
2021.4.12-->2021.4.12.2-->2021.4.15.6-->2021.4.15.8-->2021.4.15.10-->2021.4.15.12-->2021.4.18.2(merging with main branch for a bit)-->2021.4.18.11-->2021.4.21.3-->???
main branch seem to be
2021.4.12-->2021.4.15-->2021.4.18-->2021.4.18.2-->2021.12.25.6-->2021.12.25.7-->???
Some small number of the 2021.4.18.11 joined this branch too at 2021.12.25.6 same from 2021.4.21.3, but the number is maybe 15% total of the ones initially on the separate above path.
Some very small of number from 2021.12.25.7 went to 2024.24.1 (no typo) then 2021.24.2. It does not seem yet to be sure that this is the main branch evolution, the biggest concentration is still at 2021.12.25.7 from where only Tesla know when/where they will go.
The radar-less cars went to 2021.4.18.10 and stayed there until recently when some seem to be moving to the 2021.4.21.3
There are also a lot of the older MCU cars on various versions of 2020.48.37.x
There is also a completely closed to outsiders branch for the testing of the Beta FSD going thru 2021.4.18.12 and 2012.4.18.13 that only the closed beta testers can follow.
In short, for the TL;DR crowd, no one knows for sure how Tesla deploys their software, but they are testing stuff for some car populations for a bit (or longer) before merging branches. There is no way to know 100% what path a specific car will follow.
Hope it helps

I don't think it has anything to do with the Neural Nets but more with the chip pivoting that Elon has indicated over the past two investor calls. They have to change to different chips, which means re-write of the firmware (his words). They have had to pivot a lot since January when the normal chips they need became scarce.
This screen graphics is from the Q2 2021 supporting PDF found on their Investor Site.
Nope, as for example, my car is a 2020 M3 LR-AWD, from way before this mess. The different controllers and their required different firmware are usually handled at a lower level. The highest level software should be agnostic of smallish hardware variations
I can answer the ???, it is 2021.12.5.7 as of earlier today
I'd add another couple steps, 2021.4.15.12 actually went to 2021.4.18 briefly (which I didn't download) before getting 2021.4.18.2 and then 2021.4.18.3.
A large number of 18.10 have moved to 21.3 with more and more getting the update as the day and night progresses A large number of 21.3 have and are moving to 12.25.7. I stand by my original theory.
Have you been keeping up with liking Elon’s tweets? Sounds like a issue with your tweeting most likely.
Hope this is the case, I finally went to 21.3, only changes are ACC is now 2 instead of 3..nice addition, but still doesn't allow 1 like Radar cars. And the Red lines for lane avoidance.
Otherwise, 21.3 is kind of garbage, driving isn't improved, really see no other changes/updates worth a darn.
Clearly Tesla is in a bind with the chip shortages, going to pull a Apple and start designing and building their own I guess...doesn't help us HW3 people and vision only cars.

Also what is with this sudden desire to miss out the major (week) version identifiers from version numbers? So the year is pretty self evident and can be excused if missed, but major (week) number is pretty important even if we have temporarily moved away from any strong correlation between week number and when its actually landing. 18.10, 21.3 etc. What ae they 2021.18.10, 2021.4.18.10, 2021.12.18.10 ? Yes I know the answer after a bit of thought, but not everyone will.
