Fog lights plus > 70mph?

The fog slows it down, like how a small child slows down a car when it hits them!
 
It's more of a cushioning effect, seeing as it's effectively a cloud.
Xenons pierce through and vaporise it though!
 
ok let me spell it out

the fog lights are aimed low, casting a light only a few metres in front of the car on the ground. Once travelling at 70mph you cover 1.16 miles a minute. or 1.86km. Thats 31 metres a second.

Now your typical dipped headlight beam can easily stretch for longer than 31 metres, making them quite usefull in the dark.

However fog lights, only illuminating say 10 feet in front of you, are completely useless at illuminating any visible stretch of road when covering 31 metres every second. Simply, by the time the fog lights have illuminated it, you've driven over it and beyond its visibion before you've got chance to react. Driving with only your fogs on is barely any different from travelling with sidelights on. And you wouldnt do that on an unlit motorway in the dark.

Thats the point we're making.

Yeh, but it was the way Gilly said it, his post intimated that the light coming from fog lights was slower than normal lights and as such you could overtake it, which is blatantly incorrect, unless it's just under 299 792 458 m/s slower :)

Exactly. That is the part I had problems with. Gilly said:

Are you saying that fog light travels at 70mph or less :confused:

I'm saying that the light from fog lights travels slower than the light from 'normal' lights.

This is so that the light doesn't show up in dense fog like normal lights, blinding you to what is going on. IIRC it is something like the fog stops normal light getting through, whereas slower moving light moves through the fog more easily.

The problem with this is it doesn't work on motorways as you end up overtaking the light.

Oh dear... and to think I was convinced you were joking...

I still can't tell if you're joking or not, and I'm falling big time for the bait! :p

I don't think he is, I think they're actually convinced that fog lights have a magical science defying ability to reduce the speed of the light they emit by some 671 million mph so a car travelling at 70mph can overtake it.
 
Trolling is against the rules.

Gullibility should be too.

Trolling is a deliberate act, gullibility is not so making it agaisnt the rules would be a little off, either way it was an honest mistake to make considering the ridiculous claims some internet users make and believe absolutely, my apologies for not knowing you well enough to pick up on the fact that it was a joke.
 
I would have said stupidity had you not been able to see it as a personal attack ;)

I don't think anyone could say cars are faster than light...
