Do not worry about what goes on back there behind you. Ignore it. Willfully.
DO keep enough room around you to toss Anchors if you need to. Never mind the tattle tales that will light up safety like a christmas tree when you avoid a numbnut who got under your wheels. Just keep a camera of your own rolling, you will need it.
One year about roughly 1997 I think I-45 into Houston for about a hundred miles became a rush hour extraordinaire I had possessed a ungoverned tractor for a while. 90-100 with the herd of cars all doing faster was something else at 6 am in the morning some days.
Im thankful no one did something stupid like stop short in that. I would have had no place to put her.
If you are in texas and have to be at work a hour from your breakfast 100 plus miles away...
