Kal, I've never driven a Pilot car but I've followed a few. ;) Usually truckies can work in with and around each other very well. Most car drivers , on the other hand, have the attention span of a goldfish. Once the Pilot vehicle's out of sight they forget about the following load, then they've got to pass the extra guide post before they pull off; I wish I had a buck for each time I've been baulked by oncomming cars. You can hear wide ones being called long before you meet them, so it's not as if they pop up out of the blue.
