What was said above matches my understanding.
Apologies not answering OP, but for other peoples interest, my personal scenario thoughts on FSD are...
We keep our cars for a long time (my last car I changed at 14 years, our current family car is 12+ years), so I opted for the FSD. Its likely got some critical hardware missing needed for FSD (ie to support V2V and V2I) so I hope that as promised in the past with upgrade to whatever is needed for FSD will be free, will be honoured. I kind of view it as an insurance policy that is consumed into the overall cost of the vehicle, where as 7k or whatever it is in the future would require much more consideration. Will be p.ssed off if an after delivery upgrade is discounted in a fire sale as Elon only said it will go up in cost - but then, from experience and reading various sources, Tesla pricing is somewhat volatile so it would not surprise me.
I use to work in Transport Research so you would hear things and know things (we have/had a full level 5 vehicle roaming some parts of London for a few years now concentrating on human factors) and I think some self driving features will mature rapidly, but others will not - personally I don't care about 100% L4/5 FSD, but there are some assist features available now and hopefully in the future (ie greenwaving traffic lights that will require V2I) that I am very much interested in and would expect to become commonplace in lifetime of the vehicle.
I'm new to AP and what I see on tinternet is both awe inspiring (especially how good it can be outside of its current official use cases) and terrifying (when it incorrectly reacts to some scenarios well within its official use cases). I believe that, especially with more powerful hardware, both the good and the bad will progress and improve rapidly, making the system better at what it does now and open up more official use cases ([some?] roundabouts and [some?] non freeway driving), but still assisted, not FSD. Personally advanced summon looks to be a gimmick (but admittedly a high risk [risks becoming something to be mocked] company technology showcase) that unless it can navigate its way around a big supermarket car park, amongst all the other cars doing the same when its suddenly started p.ing down, it will remain so, especially in Europe that seems to want to slow autonomy up - I can see both sides.
I am personally surprised at the number of people locking in FSD that would appear to be short term owners - finance, have car 2-3 years and upgrade etc. I'm not really sure that in this time, FSD will be anything more than a slightly better EAP. I can see that for some, FSD (and previously EAP) would be a big help, but for many others (including ourselves short term - we probably average 40 miles on motorway each week) just an occasional novelty. AP now gets TACC which was the previously glaring omission for AP, so its on a par/even exceeds other manufacturers offering at this price point. The important bit about FSD is that currently, you can upgrade to AP after delivery. Apart from cost, no decision to be made - whether this remains the same when AP4, 5, 6 etc comes our remains to be seen. I don't think it will add any value to the car - its possible that if Robocar gets off the ground in 3-5 years, some of these cars from short term finance will become part of a Tesla owned fleet - in which case they will just add FSD at no/little cost to them.
Just my 2p
