Some Russian drivers now mark their driving skills.
Such tradition came to us from the age of World War II when pilots painted a star on their aircrafts for every successful enemy turned down by them.
So Russian drivers think they also are some kind of military pilots and all the other participants of traffic are their direct enemies, so the collision with everyone is something like a little victory.
So they put such kind of stickers marking successful accident with each type of traffic participants:
The railway mark probably means how much he passed on the red light through the railroad crossing.
This pilot has no pedestrian marks, he is probably some sort of human loving specie.
