I don't *want* fancy electronics my car that doesn't adhere to some standard interface.
I want music to adhere to a standard interface, EG: RCA connectors. I don't expect navigation in the dash - I'm perfectly happy using my phone. I'd be good with it playing through the soundsystem via a standard interface, EG: bluetooth.
If you take care of them, cars last a long time. I'm *still* driving a 2001 Chrysler convertible, and it not only has a CD player, but also a cassette tape! I can't imagine using CDs or tapes - all my music is in my phone. The car only has 120k miles, I'll probably get another half decade out of it, at least. (And yes, I'm aware that the Chrysler convertibles have a bad reputation; emphasis on take care of them )
I want my car to be a car, and not try to include technology with a life cycle of 3-5 years. I don't *want* my car to have a built in cellular wifi, because the cellular network will likely be upgraded well before the car dies, making the feature worthless at best, but more likely a security or reliability concern. I don't *want* my car to have built-in navigation, as whatever system it has will be hopelessly obsolete long before I'm ready to turn in the drivetrain.
Instead, I propose that cars can have an in-dash screen that may (or may not) have it's own "smarts" but is also usable as a simple screen via something like HDMI with touch feedback so that later, I can use some new whiz bang thingie that hasn't been invented yet.
