I’m sorry but that is an insane interpretation of turn signals. If you only turn them on once you’re about to execute the maneuver, they’re useless. The whole point of them is to warn other drivers you intend to do something so they can anticipate your movement and allow you to do it safely.
How are turn signals explained in the driver handbook (or equivalent rulebook) in northeastern US? As far as I know they clearly state that turn signals are about intent, so they should be turned on the moment you decide you need to turn or switch lanes.
