Here's another idea, again, click the image for a larger view and feedback is appreciated! This one would be more difficult to achieve but I think it has potential. The main problem I see is judging whether or not the laser has gone off the track (in which case it would be game over for the player). This would be a major issue if the track was moving at a high speed as it would be easy for the player to clip a corner on the track without realising it.
