if you're using the clutch and shifters and enter the pitlane, it dies sometimes.
If you're online in that little open practice before the race and pit in using the clutch it takes you in but cant get out, it cant work the clutch. (so if you're on tsukuba and screw up drifting the back corner and pass the imaginary line for the pit, you basically have to leave and restart in order to keep going...)
Come on now, its been the better part of a decade and you cant pit if you're enough of an enthusiast to have sprung for real equipment.
