Pichlo, the speedometer placement left center is really good regarding readability! Indeed much better than my halve arsed gauge.
Only the new horizontal top "row" could use some centering imo.
As the round icons already have perfect spacing i would suggest to center the new box and text horizontally to the center of the two round icons left and right.
The resulting top spacing to the new box will lighten up the design a little as the box now feels forced to the top imo. Also if a road is straight north and would be covered by the box, a top spacing would add a little advantage in seeing e.g. there is no turn "behind the box" but the road continues straight.
Thanks for your work and posting it. It literally kept me away from mocking up a very similar suggestion and wasting time. And you already did the code. Niice!
And thanks rinigus for your verbosity again.
Very interesting.
