In many cases, it actually speeds up the traffic

If timing is right, instead of 40mph to the red light, stop abruptly, only to restart in 2 seconds. You can coast 30mph, 30 feet before red light, it turns green, so you can accelerate from 30mph instead of 0mph. It not just benefits you but also benefits cars behind you.
