It would be great if a system were added to notify people that this vehicle or that vehicle is armed. Similar to how it works for people who are actively armed.
Ie. an Armed Hondamitsu Mono drives in from the west
It would be good if firmpoints that had a modification attached to them added a display to the description as well, since I'm not sure if there's any way to tell if a vehicle is armed, or what it's armed with, short of an evaluate.
I like the idea of concealable weapons too, however, where appropriate, so some consideration to that would be cool.
