I really hate it when my friends don't text when we're trying to make plans.
Another one I realized today is when I'm using cruise and another car obviously isn't because we keep passing each other. I honestly don't care if you pass me as long as you aren't driving like a maniac, but it does get annoying to pass a car, and then have them speed up to pass me.
I was once on a highway following a semi, and he was going pretty fast, buyt i decided to pass because I dont like following large vehicles, because they block the whole view. So i pass and get a ways ahead, and I notice that they are slowly gaining on me over the course of miles, so i speed up some, and the semi is still gaining on me, and at this point i am going a little faster than i would like to be, so i say screw it and lower my cruise control speed, they are going fast enough that they will just pull away I wont have to deal with them blocking my view of the road, and no joke, they pass me, get over into the right lane in front of me, and slow down. After gaining on me for miles, i immediately have to pass them back.
