For any doubters: using a 2025 model is a key detail here. It's the latest hardware version of the self driving computer. The older cars on the road are stuck with significantly worse FSD software because the hardware is far too weak.

FSD 14 lite, which is now available for the HW3 (~2019-2023) Teslas, is surprisingly good. I have a HW3 and HW4, and while HW3 isn't as confident and competent as HW4, it's good enough that I don't mind it anymore. My wife was planning on trading in the HW3 for a new Model Y next year, and now she might just wait a few more years.

I have a 2020 M3 on HW3 with v14 lite and it's very good. But even v12 was pretty good. I drove an HW4 as a loaner and did not notice a significant difference. I think the big difference would be on the long-tail of edge conditions, but I'm not sure.
