[MENTION=67936]John V[/MENTION], that's my point, and that's why it's a bad idea for a feature. It seems good on the surface, but when you look at the problems implementing it and the resulting problems, it's not worth it. Use your app like a stopwatch. Try to remember. In time, you get a habit of doing it and you don't lose many rides as a result of forgetting to hit start or stop. At least, that's been my experience.
