Well, once I find some more info, I'll post it right away...
Yeah that is true same here
I think that when they create a bridge between Northern San Andreas and Southern San andreas there is finally a meaning to drive out of Los Santos.
In San Andreas you drove out of the city; drove through country side, and arrived at another city. I really miss this feeling in GTA Online and GTA V.
This is why I think that a Northern San Andreas would be epic; this will finally bring back this feeling; which I missed.
I think that a possible solution to hardware limitations is this: you see a small cutscene where you see yourself drive/walk fly over the bridge/sea; (just a few seconds) and then you get the steering wheel again.
However; I hope that you can just drive yourself; because a cutscene would take me out of that feeling but it's better than a whole new loading screen...
