If I undesrtood you correctly:
Make the vehicle you're about to get in a part of your group (even if you are alone, you are a group), so that you are the leader of it... Then get in the vehicle (maybe order it to stop first) then order it to drive where the scud is, hop out of it and hop in the scud as driver and order the vehicle that transported you to 'stay in formation' and maybe even set the formation to 'column'...
No guarantees though (as always)...
