"Sounds stupid" Okay. Well, if you are in an oval race, as Mark agrees, it's almost impossible to find your pitbox when everyone is going down pit road in a line or are staggered. Hearing "50 meters" does nothing to aid you into your box. It's fine, I can run SimRacingApps to do this. If you decide it's a good idea and you want to market this product to more of the Nascar/oval crowd, then I will use yours. The other thing you could add is a "beep" at red line or shift points. Then I could get rid of SRA all together!
