Lovely almost-accident this morning with SS-Your-Lane-Is-My-Lane.
I'm driving down GA400 - a large, heavily traveled road. Where I join it, it's two lanes in each direction. A few miles down the road, the right lane branches to add a third lane, and the next exit after that adds a fourth full lane to the road. I usually stay in the right lane, so when the lane branches I keep to the right of the branch (meaning I have two lanes to my left, and none to my right for a bit, then a lane to my right at the next exit). Keep in mind, all four lanes continue until the toll plaza, a good 8-10 miles after this point, so there's no need to merge, and no lanes in danger of becoming exit only for a significant distance.
I am driving along, minding my own business, when all of a sudden the car in the lane to my right decides that my lane is where he wants to be, and he's coming through my passenger side to get there! I honk, swerve (thankfully no car to my left) and then start breathing again as he slams on his brakes, jumps into the lane immediately behind me, and then takes off to the far left lane and accelerates to far above the speed limit, nearly causing an accident in the lane to my left first (semis can't stop on a dime, folks!).
It's 8am, folks.... too early for EMS to have to come scrape me off the pavement.
