Took all of a half a gear. I think it was a GSX, because it had the grey trim around the bottom of it. Anyway, wasn't much of a challenge. He got on my ass leaving the line and I wasn't really planning doing anything until he stayed pinned to my bumper. So I hammered it from a 1st gear roll and broke the tires free to let him know I wasn't happy. I got free in traffic and waited for him. He was about 2 cars ahead of me when he got free and took off. I shifted into 3rd, flew by about 2 cars and let out, wasn't any need I proved my point.

You might want to not ride peoples asses in $30k+ cars, some of us don't appreciate it.
