There's a lot of things I like in this concept.
I like twin sliders, if we ever went full camper I'd want to keep that and have wind out awning one side and drive away the other.
The kitchen that slides across the second slider door I really like, the "oh look it's a side kitchen and wardrobe" solution works but seems to have squashed innovation. I do wonder with limited space why the full plumbing and sink, just have some water storage. The pop out torch and outside sockets are neat, not sure about the pop out grill and keeping it clean.
I also like the way the seats are done, finally you don't have to compromise on height or swivel, and no handbrake, both things VW could have fixed much earlier. The back seats look removable too for those that need to lug stuff
I'm not sure about the mood lighting. It rarely does a nice warm white well and long strip like that only needs one LED to die for it to look cheap.
The remote use given that everything is electronic anyway is neat if it's been done well. And by well I mean using a simple web page served from the vans WiFi hotspot. If it's an app then that's an issue - you don't need to have access to the majority of the stuff over the internet, just next to your van but more importantly basic web protocols are largely stable over long periods of time and likely still to work in 10 years time, will VW maintain the bespoke app for the same length of time?
