There's a lot of software in a car besides the entertainment system, you can't leave that to carplay or android. To make good cars, car companies need to be able to write good software.

nope nopr nope. Car manufacturers should engineer good cars. Leave the good software engineering to good software engineering firms.

  That is what GP is saying. There are two types of software in the car. The entertainment system and the software that drives the engines (ECU), lights, etc, etc. The car company should be good at software engineering to ensure that all software directly related with driving is done properly. And then leave the faster paced entertainment software to other suppliers.

    Auto pilot, adaptive cruise control, engine start stop controller, brakes, gas, etc, etc. Modern cars can’t drive without software. 100m+ lines of code in a car, 70-100 cpus according to this article: https://medium.com/next-level-german-engineering/porsche-future-of-code-526eb3de3bbe https://medium.com/next-level-german-engineering/porsche-fut...

      Exactly! That is the software I want the car engineers to focus on. I do expect most have their firmware provided by Bosch/Siemens or whichever supplier. But Tesla shows how much improvement there is to gain when designing cars from the ground up instead of from parts lists of a vendor.

        At the same time the Polestar 2 is an example of a modern EV built using a legacy mindset, and it is great and spends way less time at the mechanic than my colleagues Model 3.

        What do you mean with legacy mindset? The polestar 2 also contains many million lines of code, besides the software running carplay/android car.

  Yep. If it were possible to buy a car with no native infotainment and just a dock slot for a phone and dumb screen for CarPlay/Android Auto, I would. Car infotainment turns outdated, unsupported, and near-useless at breakneck speed and is generally buggy lowest-bidder junk to begin with, so why not just skip all of that, save some cash on the BOM which can be passed on to the buyer, and just let me plug in my phone which will never have these problems?

Right. There is a lot of innovation possible in controlling all the little embedded systems. But I think that "car platform" should be clearly separated from the "userspace". My sense is that why the legacy manufacturers are failing, at software, they have coupled the "userspace" to the "car platform". Updating UI in the center console is the same thing to them as updating the embedded code that controls the windshield wipers. That being said, I admit you cannot fully leave the "userspace" to apple or google, because you, for example, probably have some custom kind of sunroof that doesn't fit in whatever generic APIs CarPlay and Android Auto offer for Sunroofs. Additionally, if you go all in on Android Auto, you have no leverage when Google tries to extract more money. At the same time, competing with Google or Apple on UX and continuity is a losing battle. When I enter the car, I want my car to continue playing the podcast I was listening to. No car manufacturer can do this, only Carplay/Android Auto can. I guess the answer is to have good support for Android Auto/ CarPlay. But also have your own version as an insurance against being held hostage.

  Tesla seems to do just fine without CarPlay or android car.

    0 growth at the moment.

      That is one way to spin it. At the same time Tesla model Y is also the best selling car model of 2023 worldwide, so outselling all models that come with CarPlay available…

        I would wager that there were more cars with CarPlay and/or Android Auto sold in 2023 than Models Y, or any Tesla for that matter.
