That's not what he wants.
I'm guessing:
This (or something like it) is in the vehicle code.
numMountPoints = 7;
mountThread[0] = "sit";
mountThread[1] = "sit";
mountThread[2] = "sit";
mountThread[3] = "sit";
mountThread[4] = "sit";
mountThread[5] = "root";
mountThread[6] = "root";
mountThread[7] = "sit";
Change one to "crouch".
