That's very insightful. But if the NNs for the "Vision" is reused across different modules, that means things they change to make the city module work, may also affect the highway module. For example that 4D rewrite that was touted a while back.it does not really double anything.
This is not to say I have access to the latest Beta, of course, but the car code was long separated into a bunch of modules like "stay in lane manager" and "lane change manager" (that used to be "change to left" and "change to right" managers), "parking behavior", "active safety", ...
The "beta" and various dev builds add "city streets" module, but all the NNs are still in the "Vision" module and their outputs are reused by other modules as needed.
So it's totally feasible how on a highway a city street module deactivates and the old stay in lane/lane change logic takes over. But I have no hard evidence if that's how it works in the latest betas.
If this is true, I don't think most people would consider the NOA to be the "same". Even if the lane change logic remains exactly the same as the old, the NN for the vision being upgraded is much more of a change people care about than that.
I think most people's impression or implication however is basically people think when it shows the NOA interface, it is using the old 2D/3D labeling system that's in the public releases, and when it's showing the FSD interface it is using the new 4D labeling system.
