When you get in a vehicle before any of the bots going to it, it adds every bot to your squad. This gives you one more bot than can fit in the vehicle, because you took a seat.
A great example of this is single-seat vehicles, like the attack plane. If you get in at mission start, a bot is added to your squad, even though their are no seats.
I think it should not add the bot that was going to your seat to the squad.
