I know of a few people who have been done for driving around with fog lights on - Or people who have been called out for having fog lights on - & generally speaking it's not the fog lights that draw the attention
As Jim Boy said, in NSW, technically if there is no reason to have the fog lights on, then it is illegal to have them on. Of course, when I'm driving on the free way late at light, I feel there is reason to have them on
Ethan, it's not so much they are promoting fog light use, more that using your driving or headlights even during that day (Especially when the weather is like it is today) can be most helpful when it comes to visibility to other cars. I know that Volvo's in the 1980's used to have there driving lights hard wired as a safety measure... Kind of the same principal as to why motor bikes have their head lights hard wired.
To be honest, I think having the driving lights hard wired is a good safety measure & I have no idea why more car companies don't do it... Or at least have auto head lights so the car can decide when more light is needed...
