I see what you’re saying in that scenario, but I guess I still just don’t see the difference really. I promise I’m not trying to be difficult, just thinking of myself on the road and the difference between amber or red (or more common in Florida no blinker at all) doesn’t make much of a difference in how I drive.
Basically if I see a turn signal when I'm splitting or overtaking with a decent speed difference vs the lane to my right, I have to decide if I want to :
1. brake hard and potentially get killed by the guy behind me, since people suck at following distances
2. Try and snap off a position shift further to the left in the lane and hope he doesn't move over so fast I still can't get clear; or
3. just hope everything works out.
When I've only got a fraction of a second to make a decision that could mean the difference between life as a potato or making it to my destination safely, I want the best information I can get for that decision.
When you have plenty of time to look and see if the light is blinking in a pattern to determine if someone's about to come in, it's still annoying… but when you only have a brief single flash? It's infuriating.
