The drivers of the motorcycles are also the "hit points" for the unit, so if you reduced that count then the M/C (whether loaded or unloaded) would waste away quicker under fire.

Same goes for a truck - a light truck with 1 driver is rather more vulnerable compared to one with a co-driver. The 1 crew truck will be marginally cheaper though since the points calculator adds some for each man in a unit.
