My impression was many legacy car makers are struggling with car software, because of the lack of whole of car OS, but also because many components run software made by the component supplier.
Below the OS, level all components need to have software complying to the model, that can receive OTA upgrades and integrates into the system.
How much of that has Apple tee'd up, and do the component makers for legacy components have the resources to rewrite the software?
if the system doesn't provide OTA updates, it is really just user interface improvement.
In theory Google could do something similar, but component makers will struggle to support one platform, two platforms is probably out of the question.
If Apple was supplying all of the parts to build the cars, then software would be no problem, Apple supplying some components isn't totally impossible.
For EVs and other newer cars this might start to close the gap on Tesla, but IMO only slowly if we are talking OTA upgrades remote diagnostics, etc.
For FSD I can't see how Apple could have the data and I can't see how it would work if training was just done with simulations.
But in particular a legacy ICE car probably contains many components that haven't changed in 10-15 years and a lot of chips that can't readily accept OTA updates.
But many customers will not do a deep dive on the capabilities of the car beyond the "look and feel" of the user interface, if they have never had OTA updates, they will not miss them, So as a marketing exercise, the Apple interface may help sell some cars.
