I know I've mentioned this elsewhere, but seemingly not here: when you think about shelling out $12K for this software, better make sure your insurer will cover its replacement, if your car is totaled. Ours was, and we got no value for the software. So, you could easily buy a Tesla with FSD installed, get totaled coming out the parking lot, and be out $12K. (FWIW, we got FSD on a CPO Tesla on a car that was at a price I'd have been happy to buy without it; it was a bonus.)
On an only tangentially related note, I'm still not clear about how many people who spend $72K on their car (with FSD) are actually going to rent it out as a robotaxi. Personally, I'm not sure I'd EVER do it, but I'm pretty sure I wouldn't do it until I knew it could do things like avoid pot holes and other things like that. Even then, how many hours per day does this thing need to be abused by random people to make it worthwhile?
I wouldn't be surprised if Tesla's approach is the best way to get to this future, but I'm pretty sure that most FSD beta testers are paving the way for a future in which Tesla is the disproportionate beneficiary of the two.
