Nothing wrong with a early signal if no other turn is available. See that lane you wanna merge into and planning on swiftly flooring it with a .5 sec signal to follow? If you are thinking about merging signal it so every driver around you has multiple seconds to realize it. Makes for a safer experience. I share the sentiments of this post in My bones.
