I had a look on a Nissan Juke form to see if there was any conversations about front fog lights. It seems that the headlight switch is confusing. It's on the indicator stalk. You twist the outer section for Auto-Side-Dipped beam, inboard of that is fog light switch which you also twist. You can have the fog lights on in Auto, so once the fogs are turned on, they don't automatically turn off when the headlights are turned off.
Equally it's down to driver stupidity. I was just getting out of my van in a car park when a probably 60 something year old woman driving a Juke pulled in with all lights blazing. I politely asked her if she knew she had her front fog lights. "They are my automatic daytime head lights" came the reply, and here's the best bit, "I always turn then on so that people won't run into me."
