I play GTA2 on Dreamcast and PC, and think many years why Dreamcast port unfinished? What i mean

1. In DC version car can't damage (ps1 and PC has damage).
2. You can't change radio station in car (ps1 and pc has change radio).
3. Radio start play over and over again then you enter in car.

Why RockStar make bad port GTA2 on Dreamcast?
