Let me suggest you consider hall-effect sensing rather than optical interruption here. It could be both more reliable and unobtrusive, maybe. Probably easier to implement. Perhaps you could glue PMs to the bottom of your model cars.
Though, maybe you could glue a mirror to the bottom of a car just as easily. . .
This is juicy. Please elaborate a little more upon your application, SVP.
