I was speaking more on people that don't want to go faster. They just need to be infront of the truck. Then, once they're infront of the truck, they slow back down. It's a common phenomenon and it's really frustrating for us. Oh yeah you're absolutely right, I forgot about that. I've noticed this as well. They pass you and then go slow. Why? They have no respect and no clue how hard it is to drive a big semi. Now you're forced to pass them and then they speed up sometimes as well.
