2 posible way to implement this feature.
- Serial port to detect whether parking brake is engage or not. FrodoPlayer implement this feature. I wrote a small vb app to use this feature to stop most app being display, but haven't really implement it in my car yet. Too freaking busy.
- Use GPS speed. This option is not that really reliable but better than nothing. I am sure it isn't that hard or complicate to implement this feature in RR with current release.
One reason I didn't really implment this feature cuz I still want the 2nd screen (extended desktop or dua view) to be able to view video.
