Google internally tests location sharing and other new features on Google Maps?
Another option called "Hands-free faster route" will have Google Maps ask the user if he/she wants to take a faster route to the destination. By answering just "Yes" or "No," the driver can pass along his/her decision without having to touch the screen. Lastly, Google is planning on increasing the amount of information that it stores offline such as navigation and searches. This would allow Google Maps to run faster.
Keep in mind that these are features being tested on an internal version of Google Maps, and there is no guarantee that they will eventually see the light of day in a future update. Still, it is always fascinating to see how Google keeps improving this useful app.
