I agree, it'll help. But I don't see Tesla releasing incomplete features / capabilities from the FSD Beta program to the release version of FSD (the one currently for sale for $10K in the U.S. but which does NOT do 'navigate on city streets'.
So I see a subscription service being a positive for adoption rates of the existing product, but not the 10x 'Home Run' for the SP that I expect from a fully functional release of FSD w. robotaxi fleet.
I'm hopeful for wider release in 2021, but I'm not basing my forcast on that timetable. I'm calling for 2025-7 (and the release of the Model 1 / Robotaxi) for the full effect of FSD on TSLA's SP.
Gonna go out on a limb here and call for the 1st Gigafactory in India to be a Model 1 / Robotaxi plant, and that Tesla will buy most of the production for their own fleet, and sell just enough to fleet operators to fund the program for Tesla.
With a 50% gross margin, it could be that Tesla owns half of all robotaxi's effectively for free, while growing the revenue stream for future income, and managing net profits to minimize taxes.
Note that the combination of EV/FSD/Gigafactories will eat the world by 2040, Mars in the next Century, the Solar System this Millenium, the Galaxy in 100K yrs, the local Group in 1M years, and the visible Universe in 1B years. BTW, that's a shorter timespan than there's been multicellular life on Earth (a paltry 600M years). Amateurs!
