We just got to spend a week with an Android Auto car (our huge review is right here), and as part of our research to figure out how it works, we ran into quite a few things that are in the app but don’t work yet. Android Auto houses non-functional interface mock ups for several new features, along with a whole host of sensor code that Google hasn’t talked about.
What Google really intends to do with these is anyone’s guess, but it’s rare that Google ships non-functional code that doesn’t someday become functional. So while we’re personally not guaranteeing anything, this could be a peek into the future of Android Auto.
