The car has its own power generation though so it can do a lot more without risk of killing the battery. They can record and stream the whole time you use it.

Not my phone. I dont run spyware on it

You can turn off your phone at least sometimes. :) But this of course does not solve the problem.

What is your point here?

Theres still an LTE modem in your car sending data somewhere

I seriously doubt they're not capturing the information just because you told them not to. They're just going to treat it differently. But have no delusions that they're respecting your wishes as you think they should.

What's ridiculous is they made remote start only available from the app instead of a keyfob

it can happen easily in future moreover like wireless earbud which can be dos as they use bluetooth which was not build as security in mind , if used in hot countries they can be easily blasted which is enough to kill someone considering the shards will go in the brain . so this can easily be replicated in electronic cars as well . though these earbud manufactures had brain and have a device in earbuds but sometimes that device can also fail , i never used a e car so dont know if they have some type of device in it . but i would love to see a experiment over this

The problem isn’t e.g. CarPlay, it’s the car itself, which is usually entirely custom.

For example with Infiniti they have their own Android based OS and the only way to get a new head unit in the car is to have a full emulator. Otherwise you lose access to anything that the head unit controls.

I don’t know if open source custom car roms will be a thing until we have an LLM that’s smart enough to automate porting the rom to different models of car.

There are some open source cars, but they're very basic

The more we electrify our cars, the less feasible this is.

Decoding and sending messages to mechanical systems over the CANBUS is one thing (still difficult, but possible), but taking control over system software is another. In the us, consumers are supposed to have the right to repair their personal vehicles, but a lot of that law was established back when you could do work on a vehicle without having access to digitally protected copyright. We might have a right to repair, but that's starting to clash against their copyrights over their IP and software controls.

And that's not even getting into their eagerness to utilize subscription models - would a court side with a consumer if they decided they wanted to circumvent DRM controls over subscription-controlled car features (a car that they own outright)? It's unclear to me that right to repair or consumer protections have been written in a way to accommodate those conflicts.... Especially when cars are subject to far higher safety regulations than computers - a manufacturer could argue that they need to prevent consumers from tampering with their software systems for their own safety.

If you still own a 'dumb' car without one of these systems, it's really not a bad idea to hold onto them for as long as possible. You can always upgrade them if you want to - some people have even replaced ICE transmissions with electric ones. But once you own one of these cars with software-controlled systems, it's far harder to strip them out. Especially once they start requiring cellular connection to operate or function (or require connections to privately-owned satellite constellations.....)
