I struggled with this a lot. Originally set that ending overview at the beginning, but was worried that practically a lot of users might miss the main feature. I've heard from a lot of people that they were surprised it went into the 3D view, and I think some people might see the plot and just assume that's it.
The 3D view is cool, but it would be great if you could turn it off. After a few goes, all I wanted to do was quickly look at a bunch of different places - I ended up closing the 3D view and going back to the map view anyway.
Why not simply let users click on the map route preview window and have it expand into the full 2D route view?
The 3D route was truly a delightful experience and exceeded my expectations quite a bit so please don’t add any hurdles in front of this seamless 3D experience or it will lose the magic a lot of us are experiencing! …my 2 cents
