This was one of the big bugs prominently displayed in videos slamming Cyberpunk 2077 for its issues at launch. You would be driving and make contact with a building, another car, or anything in Night City and suddenly V would clip into a building or under the world map.
Implementing this simple fix is going to ease a lot of headaches for players, especially since they addressed the same issue as it pertains to a specific important mission.
In Burning Desire/Night Movie, it used to be possible to fall through the map if you ran into a truck. Now, both of these major clipping issues in Cyberpunk 2077 have been fixed by patch 1.2.
