In the first instance(Monday I believe), tweedle dee slowly merges into my lane, no signal, no indication that he saw me. I tried to find my horn and managed to push my thumb down... on the turn signal button. At the very same time, I was steering the PCX towards the left lane very slowly(didn't want to take my eyes off tweedle dee), and around the time I was on the dotted lines separating the two lanes, tweedle dee finally sees me and jerks suddenly back into the right lane he came from.
In the second instance(thursday), tweedle dum merges onto the freeway(the right lane), I'm occupying the lane to the left of that one. For whatever reason, I decided to cut my speed down a bit in response to the guy just coming off the ramp(he's not in my way or anything), as something(not a turn signal) hinted at the possibility that he might change lanes. He didn't change lanes like I thought he might, and I'm not exactly in the slow lane, so I figured I'd move into the left track and speed up before I get honked at from behind. Surprise surprise, my front wheel was matching his rear wheel when tweedle dum decides to make an unsignaled lane change into my lane. I squeezed the brakes and managed to avoid getting sideswiped by a few inches. Before I could think to honk at him and extend the finger to him, he speeds up ahead and changes lanes to the right again(at least he signaled that time), and promptly exits the freeway.
Is there some cue I ought to watch for that might hint at this a**hole behavior? The first one caught me offguard, but my body was evidently sending me some pretty strong signals in the second instance, so I'm wondering if I missed something that could have allowed me to do more than avoid a catastrophe by mere inches. Because frankly if I wanted to flirt with danger I would invite a porcupine to sit on my lap
