I was quite surprised when my new oven came with a sheet of paper listing all the open source software.

Another possibility: 2pt emboss, applied to car's body.

There's a competing automotive tech stack called "Automotive Grade Linux" which is being adopted by most of the Korean automakers, many of the Japanese ones, Daimler, etc. That implementation goes far beyond infotainment and the head unit, though it has hooks for both so they might not be in strict competition. VW potentially can just use their Android-based infotainment system on top of a different stack.

Interestingly, VW just joined AGL:

Android for the infotainment system, not necessarily the whole car. I'm not sure if they'll base everything off Android.
