Yes they are both bad situations but ones that you will find yourself in when your riding in rush hour traffic and only have two lanes. I move around a lot myself, I do whatever I can to stay out of the blind spot but keep a safe distance. If I do speed up, it is only to get out of the blind spot of the idiot on the cell phone not paying attention and then i get way over so I have the shoulder if I absolutely had to. Sometimes it doesn't matter because Friday afternoon I had a couple assholes who were trying to fly up in the right lane and cut back in and it wasn't happening and then one guy (mr douche bag in the new beemer) decides to just go ahead and get in my lane anyways even though he was looking right at me.
