Re bg on icons: let's keep icons clean for now. Background can be added later using QML - this is a bit more flexible and will ensure consistency among all icons in rather simple way.

Re drive icon: In the first look, it seemed to be more like a star which I confused with the bookmark. Although, it probably was smaller on web-site screenshot than it would be on device in the program.

As for correctness and distraction - agree, ideally it would not involve any walking/cycling/driving enforcing symbol. We can pull from history and put a walking man / bicycle / steering wheel, but that would correspond to the previous mode, which may differ. So, if we have icon that people associate with navigation instructions for all modes of transport that would be the best.
