Yes, there's quite a number in real life.
Landing westerly Frankfurt winter evening looked up and saw rush hour traffic moving diagonally on autobahn. Barbers' pole illusion of drift - back on instruments until past road.
Taking off or landing in snow blowing across - similar effect.
Turning visual left base at Ovda one evening with flat lighting from the setting sun perpendicular to the west facing hillside to the east - difficult to visually discern whether hillside very close and covered with small rocks or further away with bigger rocks. Needless to say it was the latter.
. . and then there's the old chestnut which gets the passengers worried - turning in hold with B747 1000' above or below.
