This is such a problem in Utah that last time I was there, the traffic status billboards over the freeways just said, "Camp in the mountains, not the left lane"

This is such a problem in Utah that last time I was there, the traffic status billboards over the freeways just said, "Camp in the mountains, not the left lane"... and the left two lanes were full with the right lanes empty. If I hadn't been driving I would have taken a picture to savor the irony.
