There is part of the A30 I use a lot where it goes up over higher ground where for some reason you get fog either lying in a dense ~5 foot blanket over the ground or sitting ~6-7 feet above the ground - had one the other day where it was enveloping normal cars but in my pickup I could see over the top of it - would see the tops of vehicles coming up at like 80 MPH in the outside lane then **** themselves when another vehicle appeared with the visibility at their level probably 2 car lengths at best!
Despite doing 20 MPH under the speed limit in hindsight knocking another 10 off wouldn't have been unwarranted as occasionally a big bank would come up suddenly where I could barely see 1.5 vehicle lengths ahead but it was gone almost as quickly as I reacted.
