How do you to make breakable windows on a Automation port Car?

Im trying to make my automation cars have brakeable windows but I cant think of a way of how to do that. Also, how do you add BeamNG number plates to Automation port cars? Another question, how do you make more parts fall of like doors, bumpers, grilles, ect?

 

to do most of that you'll need to split the model in blender and create jbeams for each door/window

Number plates are pretty easy to add as you just gotta add the flexbody and position/scale/rotation of them. The rest would take a while to explain
