I DO use my front fog lights outside fog conditions, I drive a lot on powys, and you always have the option of having a pheasant/sheep/hare/rabbit on the side of the road ready to pounce at you. The foggies help quite a lot showing these off in the bends. I do try to be polite and turn them off in traffic of course, but my typical journey is in the middle of the night, and trust me, a stray mammal is NOT something you want to meet at 1am on a hill road.
Now, annoyances:
+ Middle lane huggers, as mentioned before. In france it's actually a traffic offense and you can get a ticket for doing it. I wish it was the case here too..
+ Accordion middle lane huggers. Worst kind of ^^ they slow down. You pass them, go quietly in the slow lane... and then they accelerate gradually until they sit prettily in your mirror dead spot until you reach the next lorry you want to pass, and then flash you angrily because you have to pull out on them, despite signaling. GIMME THAT missile launcher, darling.
+ Mr 42. You KNOW Mr 42, it's been described quite a few times before. It's the usually older person who does 42, regardless. Can't pass them in town as then do 42 and you, 30. and then they'll make themselves large in the next 60 zone. Do check carefully your speedometer next time you see one. it's FOURTY TWO. not 5, not 0. I can't explain why.
+ Signals. My pet theory is that if you own an Audi, they check the computer at service time and will take away the audi and give you something else if you used your signals too much. Must be that.
But can't be of course, it's not JUST the audis, it's the very clever people who think they know a LOT better than anyone else, and the road is theirs, and they have permanent 36o vision anyway. That mean that they obviously are aware of everything, even fast moving motorbikes, or other people changing lane at the same time they do.
My opinion is that a large percentage of accidents are due to people not signaling. If ever you drive in the Paris ring road, you will see an amazing dance of really, really fast moving cars. And ALL OF THEM SIGNAL. Basically the only thing preventing a permanent, giant car crash is that you trust the other loonies oh the road to signal so you CAN pass them at 30mph more than their lane without having to worry too much about them pulling out.
My opinion is that people not signaling as a /reflex/ even if they are frigging alone on the road should have their legs borken as an object lesson. Jeremy Clarkson style
+ "Little princess on board" obscuring 40% of their back window.
