Are there any navigators that work with all those available options?

Current implementation is not as primitive as described [above](https://forum.kurviger.com/t/app-speed-based-auto-zoom/2139/28) - with only a simplistic interpolation.

The algorithm includes also visible distance based on screen size or else result would be awkward.
