Friendly Units and Enemy Vehicles feature

I've always wondered if it was possible to fix this or change it. I've seen friendly A.I. enter an enemy vehicle if a player of the same team is already inside it with them, to there own extent however they don't do as much as they would in a TX-130 Saber Tank. But if the player exits the vehicle the A.I. inside the vehicle becomes near brain dead and barely functions without a player inside the enemy vehicle and just sits inside without any reaction as to what happens near them. They can neither exit or land hits on enemy A.I. even if they tried and don't show much of a reaction to the vehicle being damaged.
