I remember many years ago thinking, "if they can have a add a SIM card on a phone, why not add one in your car? Imagine an Internet connected car?"
What I didn't think about was this would be an opportunity for ads and subscriptions. And everyday you'll own less and less of your car. I'm shopping for a car right now, I may have to just put a fresh coat of paint on my old one.
In most vehicles, you can pull the cellular capability (either a physical sim or the RF component). You'll lose telematics, but will also lose this.
Not just the ads. They are likely tracking your location, and drive events. These can be sold to your insurance company who may adjust your rates, or even drop you if they consider your driving patterns to be risky. When we got our Ford Maverick, first thing I did was disable this. Kudos to Ford for making this easy.
Downside is that we got a recall notice about the software for the backup camera needing an update. I scheduled an appointment, and it took over 3 hours. Asked the service guy why it was taking so long to flash to software, and he said our system needed an update because we had not enabled over-the-air connection with Ford which allows this to be done in the background. Evidently the download speed for this was incredibly slow according to the SG, so it took over two hours before our Mav was current, and they could apply the backup camera fix. Note: I was very suspicious about this claim. I thought it was more likely we were being purposely held captive in the service waiting area -- which has a big screen constantly running Ford ads. I guess that is OK. I had my Kindle, and was into a great book at the time, so I actually was not too put out.
