Here's one from yesterday, in Wisconsin. I'm a few mph under the speed limit, most traffic is 10 mph faster or more.
I don't cut off other traffic doing emergency moves. At the beginning of the video you can't see the higher speed traffic behind me in the left lane, no time to move over a lane and can't really judge the speed of the truck on the on ramp fast enough. The truck on the on ramp is not paying attention, or expecting me to magically 'vanish', which I can't do, due to other traffic. I'm watching him, slowing down more, and looking for openings....while keeping track of him. It's hard to judge the speed of on ramp traffic, and he appears to be empty, and 'flying'. Once he finally got onto the highway, he took got into the left lane and was 'gone'.
If you notice his turn signal comes on when he is already in front of me.
