Often players in your team are damaging your vehicles just for fun. For example when you take off with a drone plane from an airfield or with a helicopter they slightly damaging with bullets fire so its not destroyed completely but it make a plane uncontrollable and it crashes into lend. The "punishment windows" even does not appear cause the system does not consider that it was team player fault and even if window apear for punishment what it would do? (they also launch rockets in your tank for example sligthly damaging it but not destroys completely )
The single case i saw the result of punishment" was when someone crushed into me by vehicle with full passengers (i dont know bots or players) and they was "killed" i was punished for 30 minutes of "rest"
