I confess to being imperfect. Occasionally (i.e. not very often) I forget I'm on full beam. If someone gives a polite reminder 'flash' I immediately dip, as thats what I intended to do in the first place.
I don't mind an overtaking car going to full beam. They are accelerating into a risk area and need to see where they are going. I usually keep mine on full if poss until they are level with me to give them a bit more light, then dip before they are dazzled.
I don't like driving towards xenon lights coming the other way, and try not to look into them.
If you go back a few years the French gave you a very nasty reception if you did not have yellow bulbs...All gone now though.
As for 4x4s..well i've got one, and have not had any road rage/ headlight flashing in my direction from other road users, so I can only assume they have no major problem with the lights
I confess to getting into 'grumpy old man' mode when people use fog lights in good visi. I don't mind if its an old lady..she just has no idea where the switch is..its the chav/pratt brigade that wind me up more than I should let them.
Good opportunity for a rant though
