How did the quality control passed it? The lag on some of these car infotainment system just to change the sound is abysmal, someone definely saw that and should have said something, you paying $30,000+ for something that takes 4 seconds to respond to a music volume change. Whoever is responsible for that should not work there...

The quality control came last in the process, so when they 'finished' not long before the delivery date is due, QA gets a ton of political pressure to not make the date slip.

That's why test-driven design is valuable -- you iterate while testing.

What's the point of quality control then if it means nothing in that case?

Making sure it doesn't burst into flames

... whilst it's still in warranty.

If only we'd work together then the car could have a common bus system and you'd just swap out the control console on the front and choose your level of [stupid, annoying, distracting] graphics and what have you.

There's no competition in these systems because people choose the car and get lumbered with the UI on the console. Kinda like if houses had unique electrical systems and you couldn't change the white-goods.

Cars already have CANBUS as a standard thing so it shouldn't be difficult.

I think the CarPlay/MirrorLink/Android Auto thing is probably a better model though. Make the console dumb and let me connect my upgraded-every-year phone that's far more powerful.
