Agree about people being in the way. During rush hour it’s inevitable but there are the idiots constantly changing lanes and speeding up on top of people as if they are going to get to their destination much faster when they see traffic is jammed up to the horizon. In actuality they slow down everyone including their like-minded idiots.
What I can’t stand is that it seems like I always get behind people that drive too slow. I think they are not sure where they are going, or distracted by cell phone use, or have lost the ability to drive as reasonable speed, or like going 10 miles under the speed limit or something else or combination of the above.
