"Schneller als die Polizei" erlaubt is a TV format aired by VOX, showing a special police unit going after speeders, tailgaters and rowdys on the german autobahn. 3D visualizations, based on an experts view explain what the risks are and what dangerous situations can evolve from such irresponsible behavior.
For understanding purposes I might add that since it's a tv show we have some restrictions that doesn't allow for really movie like effects, - as well as the time restrictions. We have it running as a one man job taking two days to complete one show.
As for tech specs: Animation time for a show is about 20 secs, cars are from a library (no time to build them in the given time), modeled and animated in Maya, rendered with Renderman for Maya, comped in Shake, rendertime for a whole show is about 18 hours on a single machine.
