Yes, a simulation game is not the same thing as a real simulation program. It is a simulation GAME as others on the list have pointed out.

Also, as digit points out, how fun would it be to play the GAME when it takes several hours to deliver a single load? You would just sit there in front of your computer basically doing nothing, since most of the time you would just be driving on a straight freeway. Yes, that might be realistic, but would you really spend so MUCH time on this game?

Now, it should be pointed out that MS Flight Simulator actually does this. A lot of people have the game running over night; they go to bed, put the plane on autopilot, checks the status every hour or so, and get out of bed to land the plane in the morning.
There is a big difference though, because FS really is more of a real simulator, and you can actually learn all the needed skills a pilot needs within the simulator. You also have an autopilot, plus the option to speed up time.
In RigNRoll you will not have an autopilot, and speeding up time doesn't make any sense in this game.

Also, creating a 1:1 map of California is impossible. That would basically mean the development time would increase by at least a tenfold. Are you going to drive around and record every street, every house, every tree in California? Then you should do 3D modeling of all these objects, debug and test it. Good luck with that.
