Just had another idea come to me, which has probablly been mentioned anyway and I can't be bothered to add a discription right now but I thourght I should make sure the idea gets out there.

A system to prevent anyone who is carrying the flag or bomb from entering vehicles, except from seats that don't allow you to drive and allow you to use your own weapon.

Probablly just as impossible as I expect most of the ideas in my main post where, but for most of those I still haven't had anyone tell me for sure that they are impossible.
