Sometimes the opposite happens, though. The aggressive driver hits the light just before it turns yellow, and everyone who didn't drive like a hooligan had to stop. Depends on how well timed the lights are.
That said, people in general need to start coasting to a red light at least twice the distance away that they do. I've gotten passed by people where I'm coasting, there's a red light ahead, and there's no reason at all to hurry. Coming to a full stop is a waste of energy, and you should set yourself up to avoid needing to as much as possible.
This coasting trick works until there's enough of those assholes in a hurry that they all rush ahead to stop in every lane. Now all the sane drivers have to stop too. If I'm feeling plucky, I might honk and flash my brights at those "gotta pass everybody to stop first at the light" types like they're the slowpoke in the way, which they kind of are at that point. Usually I just keep quiet and imagine that they're in such a hurry because they are either about to or have just shit their pants.
Beware though, coasting past stopped traffic just as the light changes is a good way to get T-boned by another careless ass hat that just ran the other light.
The real trick is coasting to a stop in an open lane next to the person in a hurry; then if the light turns green, you're still moving and you can zoom right by them, which is incredibly satisfying.
You're blocking access to the turn lane by going slow a half mile before YOUR light. I don't know where you live but the major road through my city is like that. Right and left turn lanes at the light, two lanes leading up to it.
So now it's half a mile? Two lane roads like that aren't going to have dedicated turn lights, just a blanket green yellow or red for all traffic coming from a given direction, which is almost certainly what the initial user in this thread was talking about before you invented that left turn light.
And even if they did slow you down, so what? Waaaah you made my drive last another 30 seconds like big fucking deal, if you haven't yet figured out you should give yourself some buffer time when you plan your drive that's on you tbh.
Or you could drive like a normal person and drive the fucking speed limit instead of acting like you're the only person on the road. But hey, you do you, just don't cry when people like me fly past you. (we know you will, and your tears fuel my right foot)
The coasting thing is how I ride my motorcycle. It's so satisfying when you don't have to stop and put a foot down for a light because it turns green while you're still rolling.
