There isn't a specific "track car" module but instead that capability is made up from several modules. The reason is that each case can differ in a way that we cannot predict which would require a change to which modules are used or at least their parameters.

Most of the car counting techniques will use movement detection as a core module. Note that you are not really tracking cars ... but instead looking for large amounts of movement. Most tracking techniques use this and assume that within a movement amount range the object is a car. This assumes the video stream is pointed at a road or somewhere you'd expect cars to be.

If you look on the page that you mention, there is a download link to download the robofile (RoboRealm configuration) which is a text file that includes which modules are to be loaded. The example provided uses a video file as the source but this can be removed or changed to different video sources.

You can use that file by right-clicking on it and saving the target. You should get car-track.robo which can then be dragged into RoboRealm to show what modules are being used.
