The product of my wasting time with combinators for hours on end has finally paid off. I present this racetrack map that has a built in light display that keeps track of your laps and time. I was inspired by this topic and I wanted to make my own racetrack that takes advantage of the power of combinators to keep track of your time and let you see it on a big display. This is what I came up with. A line of pressure plates marks the start and finish line. The timer starts when you drive over them the first time, and stops after you've crossed them after doing the set number of laps. The pressure plate surrounded by the blue chests resets the timer after you finish. The plate by the yellow chests lets you increase the number of laps to drive and the plate by the red chests sets the laps back to 1. This racetrack needs the Pressure Plate Mod to accurately time when you cross the finish line. Of course you can drive the course without the pressure plates but you won't be able to time yourself and the racecourse isn't that special.
You can watch a video of me driving the course to see the timer and lap counter in action here.
EDIT: I changed the video to also show how to change the number of laps and added some sick beats from Initial D. Plus I took about 1 second off my time
