Personally that tech shouldn’t exist. People rely on it and don’t give others around them enough time to realize a lane change is about to happen.
Turn it on. Let it blink a few times to make sure others know you are moving. Change lanes. After you are in the lane then turn it off.
To be honest this just creates problem. Put a loud chime on it so it starts singing after a while. What we have now is a tech that allows people to signal to short of a time potentially creating accidents
