I have to disagree. A two person vehicle can be balanced under the follow circumstances:
It's movement is marginally faster than the armors.
It's health is marginally more than two and a half of the heaviest armors that can enter it.
It's weaponry is marginally more damaging than one and a half of the heaviest armors that can carry it, and is easier to use than a normal version.
Now let me validate these stipulations.
1. It's movement is marginally faster than the armors.
This of course, is how most vehicles will be balanced. They will be slightly faster or more likely slighty slower. Since this is a two person vehicle, it should go slightly faster, to make up for the use of two players.
2. It's health is marginally more than two and a half of the heaviest armors that can enter it.
This of course, is assuming it has shields. A vehicle is not as good at maneuvering than a person. Therefore, it must have more armor than a normal person, or it's protection is worthless. I actually prefer the 3-4 times the health of all occupants rule that some games use to balance vehicles. Of course, those vehicles do not have shields.
3. It's weaponry is more damaging than one and a half of the weapons of the occupants, and it's easier to use than it's normal equivalent.
Note that the damage output per a second is lower than both people alone (so that the vehicle does not dominate) and yet is easier to use than it's normal counterpart (so that it's worth using at all).
