Maybe we can make a way to show this with an icon or something similar. I feel like an alert would be distracting every time I turn my blinker on under 45mph.

I think a small, one-line alert with no sound should be fine.

True, 1 line alert would be okay

I was looking to solve this , however I saw that, it is already implemented something like this. Doesn't this function does what you were saying.

It is called at :

The alert was already implemented. I added new state to check if it is below min speed.

I saw the unit tests fail for this PR, doesn't the belowSpeed field need to be added to the LaneChangeState enum in openpilot/cereal/log.capnp?

  enum LaneChangeState {
    off @0;
    preLaneChange @1;
    laneChangeStarting @2;
    laneChangeFinishing @3;
    belowSpeed @4
;  }

Thank you sir ! I was looking for this. I created a PR for cereal. commaai/cereal#129

Is this something that you would be interested in? (Displaying a small lane change ready icon if the desired conditions are reached (enabled + vego > 20) I will make this easier to see if you give the go.

Edit:
Anyway this is something that I planned to add quite a while ago, so this is what I'm thinking it would look like. (Ignore the other icons on the screen, just the small ready icon in the upper right corner)

@HaraldSchafer Do you think this is still an issue now that the lane change speed is lowered?
