I hate it when semis make blockades on the interstate.
It happens so often. The problem is that when a truck wants to go around another truck, it takes a really long time because they're both larger than an average car.
So they end up blocking off the rest of traffic for a while as they maneuver.
This is so obnoxious to me because honestly, do you really feel the need to go around this guy? You're BOTH driving slower than most cars would like to drive. Just stay behind the other truck and things will be much smoother.
