Fortunately the only reoccurring bug I've seen is dropped objects and bodies clipping through the terrain and can no longer be interacted with, and even that has only happened maybe 10 times so far.

I haven't played a recent GTA but yeah, Cyberpunk is pretty limited as far as general inactivity, with the vast majority of people and objects are simply there for show.

I feel like they could added more content but it would have cost them most of the console peasant market.

The parkour is a pleasant surprise though, they are some interesting places to explore when climbing, and to take in some stunning views.
