Please make the 3-d visualization optional

I'd love a way to just have the route shown without then needing to do the whole 3-d "move along the route" thing.

There's been a lot of discussion on the best UX here, which I won't rehash. Based on what I've seen, I will:

• Keep the autoplay timer by default but add a little options box/drawer with an option to disable autoplay.
• Add the autoplay timer pause on mobile
• Trigger abandon autoplay on "escape" key press

Should be able to update at some point in the next couple weeks
