People who honk when the light turns green are perplexing.

People who honk within 0.5 seconds of the light turning green are assholes.

But if the light has been green for 2-3 seconds and the person at the front of the line isnt moving, then they clearly arent paying attention. The honk is warranted. The rest of us dont wanna get stuck behind another red light because youre playing with your phone.
