A bumper car area in Bash TV.

I want those groovy authority cars! with upgrades!
At least a standard shooter deathmatch mode, with like 4 maps. ~ easy for the community to add to. (give us id studio plz!)
Survival also sounds pretty cool!
A nice big arena with bosses, or a few arenas, also at least 2 of the giant bosses that we can shred up with the bfg.

Perhaps there could be a map where the Cyber demon is being constructed in part of said arena!
Maybe if there is a new mission or 2 for single player, we would have to go on foot, something went out in the car so we have to hitch it.
While walking around in this new out doors landscape, searching houses/shacks etc, we find a dirt bike or what would really be neat is a small helicopter where we could really get a good look at the scenery. Then there could be some flying dudes after us.
This game is awesome, finished it, but want more!
And I think the doors are open on the side of mod making!
