This could be useful as a communication medium where the car transmits data through the light to the neighbours.
If only there was some kind of universal communication technology that didn't require line of sight, worked over distances out to say 100m and was reasonably inexpensive to implement...then we wouldn't need to communicate using the modern equivalent of semaphore.
