Locking driver ( vehicleName lockDriver true;) and cargo ( vehicleName lockCargo [0, true];) works fine on keeping AI from entering say a bicycle, and more importantly it keeps the 'get in' icon from appearing when you're scanning for locations for a team member to move. On the M113A1 M2 (transport) for example, with the driver position locked as well as the turret and ALL cargo positions, all the same commands don't stop me from being able to move a team member into the vehicle, and the 'get in' icon still appears even though I've locked every possible position.

[_soldier1] allowGetIn false; - seems to have no effect either.

Locking the vehicle altogether kinda works, in that the 'get in' icon still appears, but the unit will report he can't enter if ordered.

this lockDriver true; this lockCargo true; this lockTurret [[0,0], true]; this lockTurret [[0], true]; - this will lock all positions on a Marshall and no icon for 'get in' will appear for team members, but the same commands won't work on an M113.

Thanks again for an awesome DLC!
