I don't mean to take the spotlight but something similar happened to me. I was at a stoplight behind a red SUV in the middle lane (three lanes). The light turns green, we go. The SUV is driving very slow so I change to the slow lane. After I change lanes, the motherf*cker in the SUV starts drifting into my lane. The asshole is literally half in my lane and half in his lane. So at this point, I get pissed and I punch the gas and move further right and go around the SUV. I can do this because the right lane is extra wide for cars turning into the parking lots without slowing down traffic in the slow lane. I'm going about 60 MPH on a 40MPH street.
After I pass the SUV, I look in the rearview and see the asshole change lane. He starts revving up and starts catching up to me. I estimate his speed at 70MPH. Well, as I'm coasting at 60MPH, there's an old 50's car taking a really wide really slow right turn. I mean the guy must have going at 5MPH if that. Also, there's a Chevy truck waiting to pull out. I'm coming up to this guy really fast and realize that he's going very slow so I slam on the brakes. I was saying to myself "Oh sh*t, I'm going to hit this guy." I look in my rearview mirror to see the red SUV coming up fast. At this point, I'm like "Oh sh*t, I'm going to get sandwiched."
Anyways, I don't think the red SUV saw the car that was taking its sweet time turning into the parking lot. I see the red SUV pull to the right side and try to pass on my right in the extra space that cars use to turn. I think the SUV driver thought I was f*cking with him by slamming on my brakes for no reason. As my car gets about 5 foot from the rear end of the car turning (I'm still traveling at 20MPH), I hear a loud screeching from the red SUV trying to brake and finally slam into the guy turning into the parking lot. The turning car is spun perpendicular to the SUV and hits the Chevy truck that was waiting to pull out. And because the turning car was pushed forward by the SUV, I was able to stop accident free. Had the Chevy truck not been there, I believe the turning car would have been launched and possible flipped.
