This UI has the same problem that a lot of other touch screen automobile UI's have; Controls are way too small. The best UI concept I've seen is for future automobiles is still Matthaeus Krenn's New Car UI. It doesn't rely on a user actually looking at the screen, but instead is based on multiple finger gesture based inputs. There are accessibility concerns with the Matthaeus' concept, but I think building on a gesture based foundation is a lot stronger of a position for the future. Matthaeus' initial conjecture actually addresses issues that are present in this Tesla UI as well as the current Tesla UI. That being said, these improvements to the Tesla UI look a lot more aesthetically pleasing than the standard UI. This concept would also be great once Teslas are self-driving and you don't actually have to look at the road since the interface offers a lot of great information at a glance.
It's worth noting that Matthaeus works at Apple today.
I don't really get the desperation for touch screens in cars, it takes away the one key feature that keeps my eyes on the road: tactile feedback. The 4-6 most common controls should be physical (volume, temperature, etc)...make the customisable for all I care, just keep my eyes on the road.
I feel like the controls are too small to be practical for a car console. Granted the controls on regular plastic/wood/metal/whatever consoles can be roughly the same size, but you can feel them and grow familiar with where to place your hand much more easily than you can with a modifiable screen UI.
However, aesthetically I prefer this to what I have seen of the Tesla UI.
Everything is waaay too small. Not only are the buttons too small to tap, the text is also small and hard to read. The UI looks good for a desktop app, though.
