Yeah I think we're all pretty well aware of this.
Having a moving steering wheel, gauges in the dash, moving shifter, and that kind of thing are on the plan for future development. This may be a focus for the next release. Of course we'll need models for all this too, so all you modelers out there, start playing with the car models in our art repository and polishing up those interiors.
As for 2D/3D, I say why waste time on 2D when we could just model it all from the beginning. Some of our cars already have a good start on an interior. They just need to be finished and made to move...
