Serios ? You are joking?
What is so difficult do know, when the view is under 50m take on the rear fog light ?
Very children knows that, in European.
Remember, American's don't know what a meter is...
Also, the US does not have nearly the level of driver training required in Europe. You basically have to be able to pass a 15-20 question multiple choice test on driving laws and road signs. In some places you have to take an in-car driving test (although I've never had one...).
When it comes to fog lights, many people here think they are "driving lights" and use them at all times. Very annoying...
