I doubt that the cheap steadicam would work well in a car, it's far too tall.

Now, I didn't experiment with this, and it works well for the stability of the shot. if your car has good shocks (doesn't shake much when you hit small bumps in the road) then it works to have a partially unfolded tripod set up on the floor in front of the passenger seat. I imagine you could do this in the back too, just slide the passenger seat forward.
i did that with one of the chunky tripods from uni. was great until i accelerated and the whole thing fell over and got some nice footage of the roof of my car.

i ended up taping it to the seat, but even then, it was still too bumpy, so i bolted the camera to the parcel shelf.
