GrapheneOS requires specific safety hardware that, as of now, is usually available only on the Google Pixel line of phones. If your standard smartphone doesn't include it, I doubt a car does.
Android Auto is a specific system that mirrors app contents from your phone. It's basically an extended monitor for your phone with specific formatting to be car usage friendly. It doesn't do anything about a car's embedded systems
Which question? The one you asked who was the huge privacy concern? If so...did you read the article they linked you? Because the answer is there, and I'm not going to read it for you.
The one you asked who was the huge privacy concern?
You are not the person I asked, nor is the last person who replied to me, so I don't know how you, they, or the article could possibly know who they were speaking of.
Plugging your phone in doesn't suddenly make your car or your phone more or less private so I don't understand the relevance.
They answered the "who is the huge privacy concern" with the link. I literally just said that.
so I don't know how you could possibly know who they were speaking of.
I read the link that was the replied to you, and applied context. It's not hard to understand what a person means when they literally write it down. It's one method of communication. Or do you constantly read articles, and never know what the authors meant unless you can quiz them directly?
Plugging your phone in doesn't suddenly make your car more or less private so I don't understand the relevance.
They weren't necessarily talking about making the car more or less private via plugging in the phone. The original comment in this thread was wishing GrapheneOS was on cars, and then "modern cars are bad for privacy" link. They were talking about the existing poor state of privacy on modern cars and wishing it was fixed via wishing GrapheneOS could be flashed to the car. There was nothing in this thread about plugging your phone into the car making it more or less private. Again...context.
You are right and they are wrong. The person you're responding to is completely irrational and unintelligent. As somebody that doesn't know them, I look down upon them and will probably periodically remember their foible and think lowly of them again and chuckle while thinking: "hah what a complete idiot". Rest assured that you won the argument and that no matter where the person you're responding to gets in life, there's at least one person who will periodically remember him and think down upon this simpleton of a person and think of you as the person who made them look like that. Hats off.
