...people running...with their (LED retrofit) fog lights on with no fog (another new trend)...
Definitely not a new trend. If you put custom fog lights on your car, it's almost certainly not for use in the fog. It's to prove how "cool" you are to everyone else on the road. You're gonna use them all the time. And probably have them aimed up so high that they'd blind you if you ever did use them in actual fog.
Just like those yellow safety light bars on personal trucks with plows. It seems some guys run those lights all winter, even when not plowing, again obviously trying to prove something. Or compensate for something.
