I've found most people, even truck drivers, are semi-asleep on the highway, no pun intended. A faster car approaching in the mirrors does not register consciously as a car that is going to pass them. Instead it the car in the mirror only wakes them enough to realize they are just following along behind the car/truck in front and decide to change lanes intending to move up in the group. Many times, they don't even signal. Especially if it is the last vehicle in a group, and even if they have let some space get between them and the group. And it doesn't matter which lane you are in behind them.

That is why I always slow and am prepared for the vehicle to pull into the left lane when approaching the first car after an open space when going faster than traffic.

Sometimes I've had truck pull over to keep me from passing and there was a highway patrol ahead the truck was slowing me down for.

Then again, every once in a while they are just road nazi *ss wipes.

When I made my record overall trip speed from Rolla MO to OKC, 400 miles in 4 hours including stopping for gas and food on a 4th of july weekend, I noticed several times that the trucks were cock blocking traffic. As I politely worked my way to the front of the group they had created they would move over and let me go by. A few of those times the truck drivers in the group worked the traffic to make it easier for me to get thru the group. I figured I was the subject of CB radio conversations and they were specifically letting me through. Really enjoyed the extra long empty spaces in front of those groups and was most likely why I was able to make such a low average trip time. Was aware they were possibly setting me up for patrol (bird dog is their term), but had my Valentine 1 and it was always clear. I figured it was just good karma because I was not driving aggressively thru the traffic. In fact, drove overly politely never tailgating of cutting anyone off and only going fast in the gaps.
