This script/mod calculate lap times for every kind of race tracks.

To use, place a sensor and name it "race.start".
Every time you pass the sensor, you get your laptime (delta from last pass).

To add checkpoints, place a sensor and name it "race.checkpoint.[YourCheckpointName]" (eg: race.checkpoint.A).
You can add as many checkpoints as you want.

Add a panel and name it "race.control" and you can:
Button 1: Switch between Race/Hotlap mode
Button 2: Reinit track if you add/remove checkpoints
Button 3: Increase total race laps
Button 4: Decrease total race laps

If you pass a checkpoint or finish a lap, you get split and lap times.
The color means:
Blue: You mark a new overall best time
Green: You mark a new personal best time
White: No new best time

Work in progress!
