There is absolutely no point in using both in fog. The idea of low mounted
fog lights is they cut beneath the fog and light the road.

The original "aim" was to pick out the kerb with the left one, and
the lane marking with the right one, nearer to the car than the
dip beam headlamps will effectively light.

All proper fog lights have a wide beam with a sharp cutoff. So can't
really be aimed as you suggest.

Nowadays, they're rather
more cosmetic than functional, and often can't even be adjusted to
aim/cutoff correctly.

Some cars have extra driving lights rather than true fogs. As you say more
to differentiate the head of paper clips car from his mere salesmen.

Headlights as well will just produce scatter and blind you.

Can do, depending on conditions, but not always.

Always. That's why foglights are low mounted and illegal in good
visibility. If the headlights were good in fog - why have specialised
lighting just for it?

But I'm talking about proper fog where you're reduced to walking pace.
