The cars themselves *are* moving in reality, it is in my fictitious *model* of the cars that they appear to be stationary. Modeling moving objects to make them appear stationary doesn't make the actual objects themselves stationary, QED.

Just set up an interferometer, and measure the speed of light forwards and backwards along three coordinates. The difference, divided by two, will give you the absolute velocity along that coordinate. Add the three vectors, and you have the 'real' velocity.
I'm surprised no one has tried this :-)
