Every car & brand will have different/unique features. My new Civic doesn't have a radar-based adaptive cruise control like my Sportage has. This results in many false braking events because the Civic's camera often gets confused. There are many things I also like about the Civic (walk-away locking included) that the Sportage doesn't have and vice-versa.
It wasn't "omitted". It just isn't part of Kia's designs. Haven't you ever owned another car brand but Honda? Thank goodness not all cars are the same!...
