I just encountered a car honking and flashing lights from behind in a straight-through/right-turn lane!

‌Wow, I'm seeing a car that feels like something out of an urban legend for the first time...
I was waiting because the light was red,
but a Mercedes GLS behind me started going HONKKKK and flashing its lights...
There was even another car in front of me,
meaning that villainous Mercedes had two cars ahead of it lol...
I'm going to report them lol
