Funny, our 2020 MY Jaguar controls car functions from the digital screen in front of the driver, the middle console screens only control AC, entertainment, phone, navigation and other non-car related stuff. No idea how the architecture looks behind all that so. But seriously, even if on the same bus, just don't the media player, radio and connected phone access to the systems actually running the car from engine to brakes. And please, please, finish developing the embedded software running on car before shipping said car. Then it can be air gapped, if not it requires OTA and internet access, raising all kinds of security issues...

And please, please, finish developing the embedded software running on car before shipping said car. Sorry, but things no longer work that way, and never will again. This is a good thing, as long as processes are improved to avoid situations like this one.

  > This is a good thing, as long as processes are improved to avoid situations like this one. How do you figure. I can’t think of a single thing in my vehicle that could be improved by software. When I buy a car I’d prefer it was done.

    It's supposedly a good thing because more features can be added over time, but if they were features worth adding in the first place, the car should have shipped with them already.

      That is the big difference between hardware and software engineering: Once hardware is shipped, there is nothing you can do besides repaurs and retrofits requiring a workshop. Software can updated and changed today anytime. My biggest issue with modern cars, and it seems this is spreading to other embedded systems than cars, is treating those as software: connect them to the web and run OTA updates everytime you need to fix a bug. That requires some form of inzernet cinnection, which requires regular security updates, which require OTA update capability. All that because, bluntly, software devs cannot be bothered with just finishing software running on non-connected hardware that just works, not can they be bothered following hardware development in case hardware is the main component, as in cars. And no, no car manufacturer is a software company, nor phone maker like Apple. The proper way of fixing software bigs in automotive used to be, again thank you Tesla for breaking something that just worked, to recall the affected cars to a workshop to conduct the software update. Honestly, the only thing on a car that should be updated by the owner is maps for the GPS unit.

  Things work like that just fine: buy an old car and call it a day. The less software in my car the better.
