Re: 100 car pile up in fog
Playing devils advocate, I feel the need to defend fog speeders......
Not a great deal of people realise that the way we judge speed is related to the level of contrast recieved by our eyes. In clear sunny conditions, there is a level contrast to the picture our eyes see and we judge speed effectivly. At night, we drive with white headlights under orange / yellow street lamps. This causes a little confusion for the brain and it see's this as an over-contrast picture and thus, we percieve that we are actualy going faster.
In fog, we get bad white out and only poor shades of other objects (other traffic, trees, scenery etc.) giving poor contrast, so the brain percieves we are traveling much slower than we actually are.
So, in a nutshell, we all know how it 'feels' faster driving in the dark, we just don't realise it feels slower in fog.
My best advice to fog speeders would be to look down at the spedo a little more often and believe what it tells you.
