I am not saying use those OSes to run the car. That's different, you do need RTOS to control, say, breaks. However, you need nice UI and fast startup time not real time OS to drive Nav, radio or an address book. Nothing is fancy there. Same as in personal computers: Joe Random User wants cool looking, fast, convenient and reliable user interface. He does not care about character based console interface even when one backed by real time OS on multicore teraflop CPU.
Maybe they should have signed up Apple... I bet Apple would love to design UI for BMW.

The UI is a result of the complexity and it will take a few iterations to shake it out.
I spent a week driving a Lexus - talk about poor UI. It starts with the very long sentence that the car speaks every time you press the Voice Command button telling you that you should speak an instruction after the sentence. It got much worse from there.

I didn't think you were implying that anyone would use those OSs. What I am saying is that the device makers you cited have experience in making certain not very complex devices.

Oh, yes Japanese cars are even worse. Their controls look exactly like those atrocious TV remotes in the first place - tons and tons of buttons, all look the same.

Here's next stupid question - How do I know if my 5er has a CCC/"Car Communication Computer"? ![Whistling](https://5series.net/forums/images/smilies/imported/whistling.gif)

iDrive is not a complex UI. There much more complex application which nevertheless much simpler to use. How many functions total are there in iDrive anyway? What's that complex in settings, radio and nav? iDrive reminds me about early TV remote controls where on/off, volume and channel buttons were same size and color as 37 others. Does one really need to check car info every day as opposed to climate controls? Why then they have equal priority on screen? Why only 4 initial choices? Why can't I customize it to my taste and place controls I want on the first page (my stupid phone can do it)? Oh, and don't let me started on six shortcut buttons in the 2008 model. Hardware buttons! Smartfully named 1-6. How intuitive! Apple design department will quite right away after observing that piece of art in industrial design :-)
The functions you see in iDrive are not all of the car's functions. iDrive is merely allowing access to some functions but the iDrive system and the CCC are dependent on and communicate with a lot of other modules in the car.
You are right re the analogy of remote control design. Of course today many companies STILL get that easy concept wrong.

You are confusing the UI with the functionality below, which I keep trying to turn the conversation back to. As I said, the UI is a result of the complexity of multiple vehicle systems.

BMW should have used two separate computers then. One to run the car and another for settings, radio, nav and all the fancy UI they want. Think client/server or, in modern terms client computer/browser and a Web service. UI computer would then send whatever information needed to the real time controller box and retrieve whatever data it needs to show to the user via some standard protocol. Data processing/gathering machine does not have to be the same as machine which present data to the user and gets user input back.

What you suggest would probably add another layer of complexity and slow down the system at this point, not speed it up. You can't think Web services when you are in a MOST environment.
