What can Rockstar Add in GTA V? List all that comes in your mind.?

When I say ADD, i mean that something that is not seen in GTA series before. Please put any creative idea which will make GTA V realistic and fun at the same time. Put as much idea as possible. Here are some I have:

1) Non-linear story line. Multiple storylines and endings depending on what you choose to do in a mission. Certain mission may transfer from one story to another. No mission fail (failing will lead to different story). Story also depend on what you do mostly (Like people who drive a lot may have a driving story and career while a shooter may be hired by a gang leader and approach different ending)

2) The map from the option looks like a small planet that moves like google earth. Have north and south pole. No edge.

3) Cars are more realistic

- Gets dirty constantly overtime and carwash needed. (I didnt find any use of carwash in GTA IV)

- A repair shop repairs the car (shown in a short video) and charges according to how much it

is damaged

- A paintshop just paint the car your favourite color. Not repair the car.

- Cars in the street are found in all shapes (some broken, some dirty, some in good shape)

- Cars lose gas and fuelling is required.

4) Trains and planes interiors are explorable (not just shown in camera). Driver doors are locked, but can be unlocked. Planes and Trains can be hijacked.

5) You can enter museums, theme parks and rides, zoo using money.

6) There are animals like deer and raccoon and a very rear huntable bears

7) Closed Population. There is no cars and people appearing from nowhere. Killing everyone and destroying all cars will leave you in the world alone. (Red Dead Redemption is kind of like this)

8) Can Carry, Use and Trade various items and can put them in car trunk.

9) Need to use washroom once in a while. If the character is hungry or need pee, it will be harder to control

10) Season change (snowy winter and clear summer). Characters max health changes based on weather. The weather also effects visibility, movement, strength, etc.

11) Trees, walls, buildings, and even grounds are destroyable.

12) Having more guns and ammo makes it harder to move. Backpacks are useful.

13) Undergrounds are explorable

14) There are politics, strikes, celebrities, etc

15) Able to interact with many objects in many ways. Like with cars, you can enter, open trunk, break glass, open hood, etc
