How to share data between multi-user in Automotive system

[조허리케인]

Dear Google Automotive team and other developers,

Supporting multi user is truly necessary for Android Automotive.

I'm developing navigation app and I need a way to share some data between users.

For example, map data is too big to store for each user.

Are there any good way to share raw data or resources between users?

And can it be the solution that using BlobStoreManager?

If yes, then.. where the data is stored via BlobStoreManager? (userdata space or any other space?)

According to the reference page, BlobStoreManager can be used to share data not between users but between apps. Am I right?

Thanks & regards,

Huricane Jo.

I have exactly the same question. 

There is any recommended approach to sharing files between users?
