This happened today in Finland motorway. Guys knew there would be crash ahead from the radio and just kept that high speed in no visibility. See the results. Most drivers drive at two second safe distance on the motorway. Over 200 crashes in that weather all over Finland from the same reason.
The drivers visibility is about two second on the video. I mean visibility not the distance to next car. That is even worse situation because you cannot even see on the sides!
Luckily no one died!.
