android auto development: sensors in a car

I'm involved in "Android Auto Head Unit" development. ( not a mobile side )

I understand I couldn't share any confidential document or something else here. However, I'd like to share something that I can share with you guys who is interested in "Android Auto Head unit.

I have just finished to skim & scan almost documents shared from google. They are already did so many things that I expected.

At this moment, I'd like to talk about the sensor information from car. As you know, currently, build app for Auto, there are only  APIs for "Playing Audio" and "Messaging".
( https://developer.android.com/training/auto/index.html )

However, mainly for the safety reason, the car shall, should, will or may provide sensor data to the Android Auto. I think these sensor data will be consumed by Android auto inside to meat specific country's traffic legal things.

What after this? I believe that google has more plan to make a best use. HU could integrate more than 20 sensors on it. ( At this moment not every sensor is a mandatory ) It's fascinating. In the near future, we can build fantastic app for AA. Such as, Eco driving management app refer to your trip and gas tank gauge, time and fuel comparison app for the same start-end point and different route including high gate fee.

I hope it will make a better driving.
