I have driven many thousands of miles and my favorite place on the road is 100 yards behind a big rig that’s heading my way. i can zone out and safely follow and people rarely want the spot between you and the truck for long so you can just go hours keeping that square centered.
It’s even better at night when the trucks lights give you a nice preview of exactly how curvy the road is.
Eventually big guy takes an exit and i always send a grateful salute cuz following a big rig 100 yards back is better than cruise control imo.
