Whilst the renders look cool as hell, my worry in where this tech is going is what happens when it goes wrong. Currently for instance, if the infotainment screen locks up then currently all you really loose is access to music and / or sat nav guidance, but the car is still drivable.
With no buttons in the car in future, and using only gestures etc. what if the software locks up (as they occasionally do), what happens to lights, heating, windows etc do they all stop working or will they have a redundancy back-up.
Can't image the dealers being too impressed by this tech either, they are still struggling with the tech that entered with the MQB platform.
