And insisting on building their own mediocre ui helps them achieve that how exactly?
Maybe I'm just super out of touch on how people use their cars, but my cars infotainment system has not made its manufacturer any additional money as far as I can tell.
Once you have the data the money can be figured out later.
You can figure out how people use the car and what features matter to them and upsell or upcharge for those features in the next line.
You can cross-advertise (oh you listen to music when driving here's Spotify deal through us and behind-the-scenes we get a cut for lead generation to Spotify).
You can use the information to defend in lawsuits. Oh our car is faulty leading to accidents? But all these people were fiddling with the unit before crashing.
Also if you control the platform you can sell integration spots to companies. I know my old BMW had a specific separate path to connect Spotify on your phone to car, no other audio app.
There's surely other ways I haven't thought of. The investment pays off later IF you get the data, but CarPlay and Android Auto have really mucked that gambit up for the car makers
