I was thinking either with a dedicated button somewhere near the
steering wheel, or otherwise on the touchscreen which you'd use at the
next stop (useless on the highway but useful in urban areas).
The "next stop" case would likely benefit from having osmand always
remember the last minute of geolocation so it can attach a piece of
tracking info to the note.
Instead of a button, I guess in theory osmand could try and recognize
a tell-tale sound, like you saying "Hey, Osmand" (in my case I'd
prefer an actual sound rather than words, like "clicking" my tongue or
snapping my finger), but I'm not sure how easy it would be to make it
work well (without too many false positives, without too many false
negatives, and without consuming too much energy).
