I think you can get an app for your phone that turns it into a lap counter. I think the app uses the camera to sense when the car drives over the finish line. I would also like to see a video of you doing some laps. Because you would literally have to drive perfectly to get laps that consistent.

When you say 14 years of racing experience, is that 14 years of sanctioned racing with a timing system and more than 9 people?
