> Any source on this? I have an engineer friend who works on the 2/3G modems for a German automotive brand. He told me anecdotally many years ago. And the public generally learned from the security breaches and vulnerability exposures. Here is one: https://www.bleepingcomputer.com/news/security/security-flaws-found-in-2g-modems-used-by-bmw-ford-infiniti-and-nissan-cars/ https://www.bleepingcomputer.com/news/security/security-flaw... As you can see in the article above, by "most" I meant pretty much everybody. Just like gorilla glass are standard for smartphones, car connectivity is a standard feature on modern cars, and it doesn't cost much to the manufacturers to add that on - given the upstream auto suppliers producing these TCUs (telematics control unit) in a massive scale, which is also why all these car brands were affected (sourced from the same supplier.) And they can up-sell connectivity based subscription features with higher profit margin.
