S550 AMG
Semi road rage-ish, but this guy attempted to merge into my lane, which would have required significant braking on my part, assuming his turn signal gave him a bye. Now, half the time I let this go and be a good citizen but not this time. Naturally, he honks his horn as I fail to let him enter, all the while on his cell as he falls in behind me.
Entering onto 400S, he then attempted to pass me on the right. At this point, the affront of seeing the AMG badge on his S550 sunk in, and I had to shut him out of his attempt rather forcefully. He again fell in behind me till he exited.
That is all...
