english: When we're out on the road, other people have expectations: So, when a cyclist puts up their arm, it means they're expecting the car to yield to them and make room for them to make a lane change.
non_english: Kada se nalazimo na putu, drugi ljudi imaju očekivanja. Tako da kada biciklista ispruži ruku to znači da očekuje od auta da mu da prednost i napravi mesta za njega da bi se prestrojio.
