FS_CRASH_CHECK Pitch and Roll

Hi

Just looking at some failsafe for my Rover. Wondering if FS_CRASH_CHECK can be expanded to include an option for pitch and roll. The Rover is running on mild terrian so if say Pitch or Roll is more than +/- 45 then its likely the rover is in trouble e.g. run a wheel up fence or tree.

Cheers
Michael
