I *think* the roundabout exit indicator issue is solved.
The use case is, you are on a roundabout turning (say) right - 3rd exit. You indicate right as normal. When you pass the second (penultimate) exit, you want to indicate left to show you are exiting the roundabout, but this just cancels the right indicator. Possibly dangerous on a busy motorway exit as you'd have to remember to press the stalk down twice.
Tried it this morning, post 2021.44.30.6 update, and it seems to be behaving as one would expect. Indicate one way then press and hold opposite way for 1/2 a second and it turns on the opposite indicator. Half press and release (either way) and it cancels.
