Unless they are actively repelling an attack, I can guarantee you that the President is absolutely not anywhere except the Beast. All of the other vehicles in the motorcade are less armored, and do not carry the critical items the President may need, namely his blood. The standard operating procedure if the President's motorcade is attacked is to exfil the President while the CAT (Counter Assault Team) lays down massive amounts of suppressing fire. To that goal, the Beast is the safest vehicle for the President to be riding in.
