Not my thing but it would be useful for checking tunes on gearboxes.
Simple track for PD to do with 1/4 1/2 & 1 mile distances with Christmas tree lights.
For the drag racers it should have timing every along every1/4 of the track & list them in the results. (also handy for tuning).
By that I mean 1/4 mile should record 3 times plus finish time so you can see how you compared vs your opponent over the whole race.
Tuning is easy because its a short "lap" for data logger or comparing against your ghost.
