I would like to see VW commit to continuous OTA software improvements, just like Apple and Google continue to improve their operating systems, or Tesla their software.
There's a lot of low-hanging fruit I'm sure VW will improve (e.g. the wasteful way the battery heated even for short trips, a very safe charging curve with low c-rate, slowness of the UI, etc), I'm not worried about that.
I am worried if VW will give us new software options like one-pedal driving (or at least a hold mode) and UX/UI improvements. The ID.4 infotainment system seems to made by two different teams that didn't talk to each other: on one hand there's a nice and smooth 3D animation of car where you just click on the part of the car you want to interact with and the same is true for the active security features interface that's actually an image of the car on a road with other cars. It's slick and pretty well thought out.
Then there's a part of the system that seems to be designed by a team that never has touched an iPad or iPhone. The keyboard is designed by them (try to find the backspace button, it took me ages to figure out it was in the text box, not on the keyboard) and also the main menu (same shape and color for all icons? Seriously?). This part of the UX is very much inspired by old in-car entertainment systems, instead of an iPad like interface like on the Tesla. The fact that the screen defaults to a menu instead of useful contextual information like Tesla is a mistake in the first place.
I think VW needs to rethink the UX of the infotainment system. It will be a huge challenge since you also don't want to confuse the people who already gotten used to the existing system.
