It is very upsetting to see so many automakers build processing into the car, like satnav and fancy touchscreen audio. That becomes obsolete much more quickly than the mechanicals. But unlike the planned obsolescence from 50 years ago where a rusted out death trap with a leaky engine gasket isn't worth the money to fix, people can still use a car for it's primary purpose (transportation) well after the in-dash MySpace integration is obsolete.
But I think there is a place for automaker innovation beyond merely mechanical tech. I don't think that a HUD is a bad idea, since even though it may only save .01 seconds when looking down at the speed, at the margin I'm sure it's a little bit safer, and maybe a little bit more entertaining, and therefore at a cheap enough price it makes sense. For in-car entertainment, they should figure out how to make better tactile UI, which barring a great advancement on haptic technology, means physical steering wheel controls that are probably the same buttons on the lock screen of your smartphone. But touchscreens aren't safe because you have to take your eyes off the road, and touchscreen interfaces designed by automakers are really unsafe because you have to take your eyes off the road for a long time to figure out how the heck to make the audio system do what you want it to do.
