Does Google Navigation Live Traffic reroute during the journey? After setting a destination and start navigation and my journey, if a new incident occurs and slows/blocks the route, is Google Navigation able to update the route and find a faster alternative automatically before I get near?
As far as I know and based on my testings with the same concern, I came to the conclusion that it doesn't update the route based on traffic or any other reasons.

I even took an alternative route that I knew it was faster in rush hour conditions and the navigator was still trying to reroute me back to its original route, considering that faster due to speed limits.
